Problems solved by technology

[0003] The main layered material used in mechanical copper plating and copper alloy is copper powder or copper alloy powder. Compared with zinc and zinc alloy powder, metallic copper is easy to oxidize, and the standard electrode potential of metallic copper is much more positive than metallic zinc. The surface state of zinc powder and zinc powder in the acidic solution is also different, so the conventional mechanical galvanizing process is not suitable for mechanical copper and copper alloy plating from the perspective of mechanism.

Abstract

The invention discloses a mechanical copper plating and copper alloy process, which belongs to the technical field of surface plating of iron and steel parts. The mechanical copper plating and copper alloy process of the present invention is by means of general mechanical plating equipment, by adjusting the pH value of plating solution, then adding copper powder or copper alloy powder and deposition accelerator in plating solution, along with the plating of mechanical plating equipment The drum is rotated to finally prepare a copper layer or a copper alloy layer on the surface of the steel part. The deposition accelerator used in the process of the present invention for copper plating consists of diatomaceous earth, sodium gluconate, triethanolamine, stannous salt, ammonium dihydrogen phosphate, polyethylene glycol, OP-10, phosphoric acid, and an appropriate amount of water. By adopting the mechanical copper plating and copper alloy process of the present invention, rapid deposition of copper or copper alloy powder on the surface of steel parts can be realized, the process is simple, the operation is convenient, and the double effect of anticorrosion and decoration of steel parts can be achieved.

Description

technical field [0001] The invention relates to a mechanical copper and copper alloy plating process, which belongs to the technical field of surface plating of iron and steel materials and is used for preparing copper and copper alloy plating on the surface of iron and steel parts. Background technique [0002] In recent years, with the increasing pressure of environmental protection, the traditional copper electroplating process has been shut down, shut down, and adjusted for a time; while the demand for copper plating process in the fields of electronics, electrical appliances, and decorative-protective hardware has continued unabated, which has given mechanical The development of copper plating provides a good opportunity. However, in the field of mechanical plating, there is no mature mechanical copper plating process used in production practice. Literature search shows that there is little research on mechanical copper plating process in the field of surface protection...
