Definitions
- This invention involves basic aspects of metallurgy, but it appropriately is in the field of rust and corrosion prevention and remediation, and more specifically it discloses and illustrates a method of remedying and of metals, mainly rusting of steel.
- Steel in various forms is the most widely used metal throughout the industrialized world. It is produced from various forms of iron ore, most commonly hemite (Fe 2 O 3 ) under high temperatures in blast furnaces. In terms of the production of steel, the critical step and key reaction is the reduction of elemental iron and carbon dioxide gas at about 1540° C. to yield liquid, elemental iron and carbon dioxide gas.
- the resultant metal product is common cast iron or pig iron. It contains approximately 1% carbon and is highly susceptible to rusting and other corrosive forces. Iron alloys tend to resist corrosive processes. Stainless steel, an alloy with up to 30% chromium and a small fraction of nickel is highly rust and corrosion resistant. Steel with higher concentrations of carbon are harder than pig iron but tend to be susceptible corrosion to and formation of rust.
- Rust is the product of corrosion, the oxidative deterioration of metal. Empirically, the process is relatively simple. Iron (Fe 3+ ) is oxidized to yield hydrated iron (III) oxide, of the form approximately Fe 2 O 3 .H 2 O.
- a minute galvanic cell is formed by a droplet of water extending over a pit on the surface of a piece of iron. Different areas of the surface covered by the droplet act as anode regions and cathode regions. Oxidation occurs at the anode region with electron flow through the metal to the cathode region.
- the droplet of water provides an aqueous phase which provides for the movement of iron (Fe 2+ ) from the anode region to be accumulated and deposited in its oxidized form as hydrated iron oxide (Fe 2 O 3 .H 2 O).
- rust prevention is accomplished by distributing the formation of the minute galvanic cell, or by destroying such cells before a significant magnitude or degree of corrosion occurs.
- Rusting appears to be a cumulative, accelerating process.
- the initial formation or deposition of rust accelerates the rate of continued deposition. This is in part explained by the roughened surface of rust accumulation resulting in, among other things, increased sites for the formation of galvanic cells and exposure to oxygen owing to increased surface area of the rusted surface.
- Rust prevention most frequently involves applying a protective coating to iron surfaces to inhibit the aqueous phase of the galvanic process. Frequently, physical removal (scraping, sanding, or buffing) of existing rust accumulations to smooth surfaces and remove accumulations of rust precede the coating process.
- the most common coating is some form of metal, rust inhibiting paint that protects the metal surface for exposure to oxygen and minimizes droplet formation directly on the iron surface.
- Other coating processes are used, including applying coatings of other, less rust susceptible materials such as zinc, to yield galvanized steel, or the use of stainless steel, which is iron with a relative high content of chromium plus a small amount of nickel. Although iron with high carbon content is harder than pig iron, it is not markedly less susceptible to corrosive forces.
- Rust remains a significant economic and safety problem. Many current efforts focus on surface treatments to inhibit rust formation. For example, U.S. Pat. No. 6,562,474 issued May 13, 2003 to Yoshimi, et al. describes and claims both a method of coating steel sheets with a zinc or zinc alloy material to reduce corrosion and the resulting protected steel sheets. Uramoto, et al. in U.S. Pat. No. 4,642,011 issued Feb. 10, 1987 described a composition comprising an organic silicon compound that inhibited rust formation of threaded metal elements to which it was applied.
- a purpose and objective of the invention is a method to inhibit rust formation of steel materials by exposing the material to a flame produced by unique hydrogen fuel or gas.
- An additional purpose and objective of the invention is a method to remove rust from corroded iron materials by exposing such materials to a flame produced by a unique hydrogen fuel or gas.
- a still further purpose and objective of the invention is a method to inhibit galvanic processes on the surface of iron that contribute to the formation of rust or to corrosive processes.
- the invention is a method to remove and/or to inhibit corrosion of steel materials comprising: providing means for delivering a flame to a steel material, said means including a hydrogen and oxygen gas generator system; generating said hydrogen and oxygen gas as a source of fuel for the flame; treating said steel material by applying a flame to a desired area of the steel material to be treated; and traversing the area of the steel material to be treated with said flame at a desired rate sufficient to remove surface rust, if any, and to inhibit corrosion of said steel material, wherein said treating of the steel material causes changes in said treated areas of the steel material so as to inhibit galvanic processes that cause corrosion.
- the flame is applied using a welding tip of a predetermined size.
- the flame is applied from a predetermined distance above the area of the steel material to be treated.
- FIG. 1 schematically describes the general features of a mixed gas generator that that produces and utilizes the hydrogen and oxygen gases used in the present invention.
- FIG. 2 schematically illustrates rust removal and prevention results on a carbon steel sample in response to a flame treatment using the unique gas produced from the mixed gas generator similar to that schematically depicted in FIG. 1 .
- FIG. 3 schematically illustrates rust removal and prevention along a cut edge of a sample of pig iron in response to the flame treatment method of the present invention.
- FIG. 4 schematically illustrates rust removal from the surface of a sample of carbon steel and the resultant inhibition of rust formation in conditions normally favoring corrosion.
- Gas welding systems that combine oxygen and acetylene gas to produce a variable temperature flame for gas welding are well known to those of average skill in the art.
- the present invention utilizes a flame produced by a novel gas produced in a novel manner.
- the fuel source for the welding flame is the hydrogen and oxygen gas mixture produced by a hydrogen gas and oxygen gas generator, which is part of the welder/flame generating system described above.
- An electrolyte solution is processed by the generator to yield oxygen gas and hydrogen gas.
- the two gasses are transferred to and stored as a single gas from which they are delivered (pumped) as a sole fuel source to a welding torch with a specific tip. Gas is delivered at a specific pressure and rates compatible with the tip in use.
- the incorporated U.S. Pat. No. 6,689,259 provides full and complete details of all aspects of a welder/flame generating system, including pumps, valves, and pressure control means from which FIG. 1 provides a brief summary as background material in explanation in part of Examples 1, 2, and 3 as illustrated by FIGS. 2, 3 and 4 respectively.
- the device or system 10 comprises a hydrogen oxygen generator 12 , an electrolyte reservoir 14 with an electrolyte 16 , a gas storage tank 18 , gas reservoir 20 , welder unit 22 with gas delivery hose 24 and welding handle and tip 26 .
- Electrolyte 16 is pumped from the electrolyte storage reservoir 14 to the hydrogen and oxygen gas generator 12 as indicated by arrow head 28 .
- the hydrogen and oxygen generator splits gas water in the presence of the electrolyte 16 to yield hydrogen gas (H 2 ) and oxygen gas (O 2 ).
- the mixed gasses are transported 30 to the upper region of the electrolyte chamber 32 .
- Hydrogen and oxygen gas mixture may be delivered 33 to the welder 22 and transmitted by the hose 24 for combustion at the tip 26 , or transmitted 34 for storage to a tank 18 , thence 36 to the gas reservoir 20 from which the gas may be transmitted 38 to welder 22 for combustion as previously described.
- the fuel is delivered as a single mixture of oxygen gas and hydrogen gas in a fixed proportion of approximately 2:1 hydrogen to oxygen.
- a second hose may deliver oxygen that is not used in the combustion process, but is used to “blow” debris (slag) from the work area.
- FIG. 2 is presented to illustrate the effects of the treatment of metal (iron) on rust removal and formation resulting from a flamed fueled by the gas described above and supplied by a gas welder system essentially as depicted in FIG. 1 and the accompanying descriptions.
- the flame produced was passed across the surface of a sample 40 of rusted carbon steel approximately 0.75 in (1.9 cm) thick.
- the flame was delivered by vector brazing tip size 0.
- No pretreatment was applied at ambient temperature of 81° F. (94.5° C.) and relative humidity exceeding 50 percent.
- No other gas was used in any phase of the treatment or as a post-treatment. Gas was delivered at 25 PSI and the flame moved across the surface of the sample at about 0.25 inches every 3 seconds, or 11 cm per minute.
- the speed of the passing of the flame over the surface of the steel can typically vary with the tip size adapted to the torch. Torch speed can also vary depending on the amount of rust/corrosion present on the metal to be treated, for example new carbon steel with little oxidation could be treated quickly, or as part of production process as a pre-corrosion process to prevent or stop the normal rust/corrosion that occurs.
- the initial rusted surface 44 is contrasted by a bright, silver-white surface 42 essentially the width of the flame applied along the full length of the application. Note shorter segments of treatment 46 and 48 illustrated the same silver-white sheen. Removal of the rust was essentially instantaneous. The rust inhibiting effect is illustrated by the fact that the rust-free areas depicted by regions (treated surfaces) 42 , 46 and 48 maintained the appearance for 30 months following treatment based on observations with 10 ⁇ macroscopic observation to confirm observations of freedom from rust, and based on observations with the unaided eye. Untreated areas 44 continued to accumulate rust during the 30 month observation period following the flame treatment. The observed post-treatment samples were exposed to “normal” ambient, corrosive, conditions of Florida.
- FIGS. 2-4 are submitted and the dotted or short dashed areas denote rusted areas of the surface of the sample of steel and areas denoted by cross-hatching or striations are symbolic of areas of the sample of steel where the surface was a bright shiny silver-white corrosion free appearance.
- the conversion was a direct function of the flaming treatment or application.
- the flame did not traverse the full length of the metal sample, the bright, rust free region extended minimally beyond the path of the flame.
- the width of the rust free area was essentially equal to the width of the flame treatment.
- the unique flame could have affected the distribution of anode and cathode regions on the metallic surface, thereby disrupting essential electron flow; microscopic changes in the metal's surface cannot be excluded. In either case, one thing is certain, the result of the treatment is significant and dramatic.
- FIG. 3 illustrates the removal and inhibition of rust resulting from flame treatment similar to that of Example 1.
- the sample 40 is a piece of low carbon (pig) iron 1 in. ⁇ 25 in. ⁇ 0.75 in. (2.54 ⁇ 73 ⁇ 19 cm).
- Interest in this example is on the cut surface or treated surface 42 of the sample.
- the sample was cut from a uniform sheet of material using a cutting (welding) torch with a size 4 cutting tip and the gas delivered at 28 PSI. The cutting was accomplished approximately 25% faster than expected using standard oxy-acetylene technology.
- the cut edge 42 displayed the same bright silver-white sheen described in Example 1.
- the cut edge remains essentially rust free with a bright, silver-white sheen. Untreated areas of the sample continue to accumulate rust under storage conditions of ambient temperature and humidity in Florida.
- Example 2 as in Example 1, the actual treatment, cutting in Example 2, was accomplished with a flame fueled exclusively with hydrogen and oxygen mixed gas generator described above; however, in Example 2, a separate hose delivered oxygen to the cutting site exclusively to “blow” slag and cutting debris from the work site. There is no reason to expect that the oxygen affected the cutting or rust prevention processes.
- FIG. 4 illustrates the effect flame treatment of metal on rust removal and prevention.
- the flame was fueled by the hydrogen and oxygen generated mixed gas and delivered by a welding device essentially as described for FIG. 1 .
- the flame was applied with a size 0 victor tip with gas delivered at approximately 20 PSI.
- the cone of the flame was approximately 2 inches (5 cm) and the flame traversed the surface of the sample piece at a uniform distance of approximately 0.125 in. (0.3 cm) from the sample surface.
- the sample piece 40 was a 0.75 in. (1.9 cm) carbon steel strip with a generally uniform rusted surface 44 . Exposing the steel surface to the gas flame resulted in essentially immediate removal of rust and the metal displayed the silver-white 44 sheen previously described in Example 2 and 3. Following treatment, the sample was submerged in a salt (sodium chloride) water solution at room temperature for 60 days. Upon removal, the treated areas appeared to be discolored, but not significantly rusted. The discoloration was removed by gently brushing with a tooth brush. Subsequently, no rust formed during the observation period of 30 months.
