Abstract

The invention relates to a cobalt nickel phosphorus-silicon carbide electroplating solution and an electroplating method, and solves the technical problems of high brittleness, poor wear resistance, low electrodeposition speed, and existence of microcracks in the surface and holes after plating in the existing electroplated tungsten alloy. The electroplating solution contains the following components in parts by weight: 1000 parts of deionized water, 1-5 parts of cobaltous sulfate, 120-180 parts of nickel sulfate, 5-20 parts of phosphorous acid, 10-40 parts of silicon carbide, 45-75 parts of sodium citrate, 15-25 parts of lactic acid, 1-2 parts of saccharin and 0.2-0.6 part of dimethyl hexynol. The invention also relates to an electroplating method. The electroplating solution and electroplating method can be widely used for surface treatment of metal workpieces.

Description

technical field [0001] The invention relates to an electroplating solution and an electroplating method, in particular to a cobalt nickel phosphorus-silicon carbide electroplating solution and an electroplating method. Background technique [0002] In the field of petroleum machinery technology, eccentric wear and corrosion are relatively serious. For the surface treatment process of petroleum machinery, there is currently no surface treatment technology that is both anti-corrosion and wear-resistant and low-cost. With the continuous consumption of petroleum resources, the environment for oil exploitation is getting worse and worse, and the requirements for corrosion resistance and friction resistance of petroleum equipment are also getting higher and higher. Therefore, developing an anti-corrosion and wear-resistant surface treatment technology has always been a subject of research by those skilled in the art. [0003] The traditional surface treatment technology is mainly...
