Abstract
The utility model discloses a double deck phosphor-nickel alloy layer film on the steel piece which comprises a double deck film, wherein, the first layer is a phosphor-nickel alloy layer film which is provided with a second layer of the phosphor-nickel alloy layer film. The first layer of phosphor-nickel alloy layer film is the phosphor-nickel alloy layer film containing 9% to 11% of phosphor. The thickness of the first layer of the phosphor-nickel alloy layer film is 5 to 50 mum. The second layer of phosphor-nickel alloy layer film is the phosphor-nickel alloy layer film containing 2% to 3% of phosphor. The thickness of the second layer of the phosphor-nickel alloy layer film is 5 to 50 mum. The utility model has the advantages of higher erosion and abrasion resistance, the common steel piece coated with the double deck film can be used to replace the stainless steel piece and the chrome plating pieces since the chrome plating is forbidden these days.
Description
Technical field
The utility model belongs to surface of the work and strengthens and the decoration technique field the double-deck nickel-phosphorus alloy tunic on particularly a kind of iron and steel parts.
Background technology
The plating principle of nickel-phosphorus alloy chemical plating process is: utilize chemical reaction with nickel ion reduction and deposit to the surface of workpiece, obtain one deck controllable thickness, fine and close coating uniformly.It regulates the phosphorus content and the Technology for Heating Processing of coating according to Service Environment and operating mode, can make coating corrosion-resistant, wear-resistant, or have both two kinds of performances.This coating successfully on the carbon steel goods plating nickel (phosphorus) layer replaced stainless steel part, can also improve the hard chromium that coating hardness be used to replace part by suitable processing.
A lot of about the patent of nickel-phosphorus alloy coating both at home and abroad at present, all be about the technology of individual layer nickel-phosphorus alloy coating or the patent of solution composition.Because amorphous phosphorus-nickel alloy coating is the homogeneous structure of homogeneous, have higher wear-resisting, corrosion resistance.But nickel coating has loose structure on microcosmic, because the current potential of nickel is with respect to the iron calibration, nickel-phosphorus alloy tunic for individual layer, when eroding away present tunic surface, corrosive medium is easy to penetrate tunic and arrives matrix along the through hole longitudinal development always perpendicular to surface of the work; Again because the nickel-phosphorus alloy tunic belongs to the cathodic tunic with respect to steel, thus the matrix that comes out will be easy to by corrosion, thereby produce red rust.Therefore individual layer nickel-phosphorus alloy tunic does not only have protective effect to the substrate steel iron material in corrosive environment, can form serious local corrosion on the contrary, influences material property.
Summary of the invention
At the problems referred to above, the purpose of this utility model is that the corrosion for iron and steel parts provides a kind of double-deck nickel-phosphorus alloy tunic that has on the higher corrosion proof iron and steel parts.
The technical solution of the utility model is achieved in that
Double-deck nickel-phosphorus alloy tunic on the iron and steel parts is made up of duplicature, and ground floor is the nickel-phosphorus alloy tunic, and second layer nickel-phosphorus alloy tunic is arranged on ground floor nickel-phosphorus alloy tunic.
The nickel-phosphorus alloy tunic that described ground floor nickel-phosphorus alloy coating is phosphorous 9-11%.
Described ground floor ni-p alloy coating film thickness is 5-50 μ m.
The thickness of described ground floor nickel-phosphorus alloy tunic is the nickel-phosphorus alloy tunic of the phosphorous 9-11% of 5-50 μ m.
Described second layer nickel-phosphorus alloy tunic is phosphorous 2～3% nickel-phosphorus alloy tunic.
Described second layer ni-p alloy coating film thickness is 5-50 μ m.
The thickness of described second layer nickel-phosphorus alloy tunic is phosphorous 2～3% the nickel-phosphorus alloy tunic of 5-50 μ m.
The utlity model has advantage, use the common steel and iron parts of this bilayer tunic plating can replace stainless steel part than high corrosion-resistant and wearability, the use because chromium plating at present has been under an embargo, so the utility model can also replace the chromium plating plating piece.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Specific embodiments
The utility model is for there being double-deck nickel-phosphorus alloy tunic on workpiece substrate 1.
Ground floor nickel-phosphorus alloy tunic 2 is the nickel-phosphorus alloy tunic of phosphorous 9-11%.
The thickness of ground floor nickel-phosphorus alloy tunic 2 is 5-50 μ m.
The thickness of ground floor nickel-phosphorus alloy tunic 2 is the nickel-phosphorus alloy tunic of the phosphorous 9-11% of 5-50 μ m.
Second layer nickel-phosphorus alloy tunic 3 is phosphorous 2～3% nickel-phosphorus alloy tunic.
The thickness of second layer nickel-phosphorus alloy tunic 3 is 5-50 μ m.
The thickness of second layer nickel-phosphorus alloy tunic 3 is phosphorous 2～3% the nickel-phosphorus alloy tunic of 5-50 μ m.
Specific implementation is: the nickel-phosphorus alloy coating 2 of the phosphorous 9-11% of lining 5-50 μ m on workpiece substrate 1, and the plating time is 1-3 hour, adopts commercially available high phosphorus nickel-phosphorus alloy plating bath; The nickel-phosphorus alloy coating 3 of the phosphorous 2-3% of lining 5-50 μ m again, the plating time is 1-3 hour, adopts commercially available low-phosphorous nickel-phosphorus alloy plating bath.Promptly obtain complete double-deck nickel-phosphorus alloy tunic.Neutral salt spray test shows that the corrosion resistance of double-deck Ni-P coating improves 4-6 doubly than the individual layer Ni-P coating of same thickness, and the time that first red rust occur can reach 384h.
When corrosion when the direction perpendicular to the surface spreads, when the low-phosphorous nickel-phosphorus alloy tunic that at first penetrates top layer runs into the nickel-phosphorus alloy tunic of high phosphorus of bottom, owing to have higher potential difference (greater than 500mV) between two-layer, micro cell appears corroding at the interface at tunic, the high phosphorus tunic of current potential calibration is as negative electrode, and corresponding low-phosphorous tunic is as the anode of micro cell.Because the electrochemical protection effect of double-deck nickel-phosphorus alloy tunic so in the process that corrosion takes place, the corrosion current on tunic surface obtains disperseing, thereby has delayed the corrosion of matrix.
With the instantiation the utility model that is further elaborated.
Example 1:
The nickel-phosphorus alloy coating film 2 of the phosphorous 9-11% of lining 6.3 μ m on the automobile steering disc carrier, the nickel-phosphorus alloy coating film 3 of the phosphorous 2-3% of lining 15.6 μ m again.Promptly obtain complete double-deck nickel-phosphorus alloy tunic.
Example 2:
The nickel-phosphorus alloy coating film 2 of the phosphorous 9-11% of (material is the 4Cr13 stainless steel) lining 12.0 μ m, the nickel-phosphorus alloy coating film 3 of the phosphorous 2-3% of lining 25.8 μ m again on piston ring.Promptly obtain complete double-deck nickel-phosphorus alloy tunic.
