3 Claims.
This invention relates to a galvanizing composition.
Heretofore in the use of galvanized materials the galvanizing has become damaged in one way or another as, for example, by wear or in the process of welding, fabricating, assembly, or otherwise.
The repair of damaged galvanizing has been attempted with the use of a tin-lead solder,
vanizing surrounding the point of repair to be.
burned and oxidized.v
Now in accordance with this invention, a galvanizing composition is provided with which the repair of worn or damaged galvanizing may be readily accomplished. More particularly,
-' with use of the composition according to this in vention a zinc coating, fused with and affording the base metal protection equal to that of the original galvanizing surrounding a damaged or worn portion, may readily be obtained; and with use of a low temperatu'reprecluding the burning of or other damage to the surrounding galvanizing.
The composition in accordance with this invention comprises an alloy including lead, tin and zinc or'cadmium or a mixture thereof, admixed with a flux. In the composition according to this invention, zinc and cadmium will be full equivalents one for the other andit will be understood that hereafter and in the claims appended hereto where the term zinc" is used, cadmium is contemplated as the equivalent.
Generally speaking, zinc or cadmium, or. a mixture thereof, will be included in the alloy desirably in amount of from about 40% to about 50%. Where both zinc and cadmium are included, they may be included in any proportion to each other, but desirably will be in the proportion of about 1-75 parts of cadmium to about 99-25 parts of zinc.
Lead and tin will be included in the alloy primarilyto reduce the melting point thereof. The
amount of lead and tin taken together will be included in amount of from about 50% to about Theproportion of lead to tin may vary,
Application January 21, 1937, Serial No. 121,593
but desirably they will be included in the proportion of about 70%30% of tin.
The flux will comprise any suitable flux having the property of dissolving metal oxide in a dry state, for example, triethanolamine, aniline hydrochloride, zinc chloride, ammonium chloride, a mixture of zine chloride and ammonium chloride in the proportion, for example of 60% zinc chlo ride and 40% ammonium chloride, etc. Desirably the flux will include a preserver, as magnesium carbonate or equivalent, in amount of from about 1% to about 3%, to negative hardening of the composition from chemical action.
The composition will include the metallic ingredients or alloy and the'fiux in proportion with the range 30% metal-40% flux to 70% metal 30% flux.
In preparing the composition, the metallic ingredients will be alloyed, the alloy, desirably, powdered or granulated and then mixed with the flux.
In using the composition for the repair of worn or damaged galvanizing, it may be applied to the work in powdered or granulated form, as with a blow torch, at a temperature of, for example, 500-600 F.
More specifically,a desirable composition in accordance with this invention, which will be readily applied without preparation, as by cleaning, of the base metal and which will eifectively combine with the base metal and surrounding galvanizing and afford protection to the base equal to that of hot-dipped galvanizing, will comprise an alloy of 50% zinc, 15% lead and 35% tin admixed in powdered form with a flux in the proportion of allow and 35% flux.
In using the composition according to this invention for the repair of worn galvanizing, or for the replacement of galvanizing which has been burnt off in welding, it will be found that an emcient coating of galvanizing, fused or amalgamated with the base metal and with the galvanizing surrounding the worn or damaged per-- present in amount not less than 40% of the al- 10y, the lead and tin forming the balance of the I alloy, and a flux capable of dissolving metal oxide in a dry state admixed with the alloy.
2. A galvanizing composition comprising an alloy of lead, tin and zinc in which the zinc is present in amount within the range 40%-50% of the alloy, the lead and tin forming the balance of the alloy, and a flux capable of dissolving 10 metal oxide in a dry state, the flux and alloy be-
