Problems solved by technology

[0009] "China Tungsten Industry" published a Ni-P-W-Mo quaternary alloy process in June 2008 (Volume 23, Issue 3), but the biggest problem of this process is that the combination of element Mo is not enough, which seriously affects the finish and wear resistance of the coating. Not enough, and not resistant to hydrogen sulfide corrosion

Embodiment Construction

[0025] A highly hydrogen sulfide-resistant and highly wear-resistant environment-friendly Ni-P-W-Mo quaternary alloy plating solution is characterized by the composition of the plating solution. The formula is: nickel sulfate or nickel chloride 28-35g / L, sodium hypophosphite 35-44g / L, sodium acetate 11-15g / L, 88% heat-resistant lactic acid 8.4-8.8ml / L, DL malic acid 14.3 g / L, succinic acid 6g / L, brightener 0.3ml / L

[0026] Complexing agent 0.17ml / L, stabilizer 0.1ml / L, sodium hydroxide 3-5g / L, ammonium molybdate 15g / L, sodium tungstate 18g / L.

[0027] The preparation steps of described Ni-P-W-Mo alloy plating solution are as follows:

[0028] Step ①, dissolve the main salts nickel sulfate, ammonium molybdate and sodium tungstate with 100ML distilled water respectively.

[0029] In step ②, pour borax into 0.7L hot distilled water and stir to dissolve, slowly add lactic acid under continuous stirring, add the main salts of step ① nickel sulfate and sodium tungstate to the ...

Abstract

Belonging to the technical field of surface treatment technologies, the invention provides a high hydrogen sulfide resistant and high wear-resistant environment-friendly type Ni-P-W-Mo quaternary alloy plating solution. Per liter of the plating solution comprises: 28-35g of nickel sulfate or nickel chloride, 35-44g of sodium hypophosphite, 11-15g of sodium acetate, 8-9ml of lactic acid, 12-15g of DL malic acid, 5-7g of succinic acid, 0.2-0.4ml of a brightening agent, 0.1-0.2ml of a complexing agent, 0.08-0.12ml of a stabilizer, and the balance water. The plating solution realizes chemical plating of W-Mo quaternary alloy, an also, except a main salt, the used materials all adopt food additives as attached salts. And there exists no heavy metal ion environmental pollution.

Description

[0001] technical field [0002] The invention belongs to the technical field of surface treatment, in particular to a quaternary alloy plating solution used in electroless plating. Background technique [0003] Electroless plating is a new type of metal surface treatment technology, which has attracted increasing attention because of its simple process, energy saving and environmental protection. Electroless plating is used in a wide range, and the gold plating layer is uniform and decorative. In terms of protection performance, it can improve the corrosion resistance and service life of the product; in terms of functionality, it can improve the wear resistance, electrical conductivity, lubrication performance and other special functions of the workpiece, so it has become a development of surface treatment technology in the world. [0004] In the 1980s, the research, development and application of electroless plating technology in industrialized countries such as Euro...
