Embodiment approach

[0093] As a preferred embodiment of the present invention, in step (d), the post-plating treatment includes cleaning, drying, polishing and oiling the plated parts;

[0094] As a preferred embodiment of the present invention, the brush plating process method includes the following steps:

[0095] (a) rough grinding the surface of the plated piece, then fine grinding, and then mechanically polishing the surface of the plated piece;

[0096] (b) Use electrocleaning liquid to carry out electrocleaning treatment on the polished plated parts. During the electrocleaning process, the plated part is used as the cathode, and the brush plating pen is used as the anode, and the working voltage is 8-12V;

[0097] Use activation solution to activate the plated parts after electro-cleaning treatment. During the activation process, the plated parts are used as anode, and the brush plating pen is used as cathode. The output voltage is 15-25V, and the activation time is 5-15s;

[0098] (c) Us...

Embodiment 1

[0106] The present embodiment provides a brush plating process, comprising the following steps:

[0107] (a) Copper is used as the base material of the plated part, and the surface of the plated part is roughly ground with a hand-held grinder loaded with 600 mesh sandpaper, and then slightly unidirectionally finely ground the surface of the plated part with a grinder loaded with 1000 mesh sandpaper. Remove the impurities on the surface of the plated parts, and at the same time mechanically polish the surface of the plated parts to obtain a bright, fresh and microscopically rough surface of the plated parts;

[0108] (b) Electrocleaning is carried out to the polished plated parts with electrolytic solution;

[0109] During the electro-cleaning treatment, the plated parts are used as the cathode, and the brush plating pen is used as the anode. The working voltage is 8V. Sodium chloride 2g / L;

[0110] Use the activation solution to activate the electro-cleaning treatment of the...

Embodiment 2

[0116] This embodiment provides a brush plating process, except that the composition of the electrolytic solution in step (b) is different, other steps and process parameters are the same as those in embodiment 1.

[0117] The electric cleaning liquid is mainly made of the following raw materials: sodium hydroxide 9g / L, sodium carbonate 50g / L, trisodium phosphate 50g / L and sodium silicate 9g / L.

Abstract

The invention provides a brushing electroplating process method, a clad layer and application, and relates to the technical field of brushing electroplating. The brushing electroplating process methodcomprises the steps that after a plated part is ground and polished, electric purifying treatment and activating treatment are carried out; and then after brushing electroplating treatment is carriedout, treatment after plating is carried out. The process is easy to operate, and all the steps of the brushing electroplating process method and the composition and dosage of brushing plating liquidare limited, so that the clad layer brush-plated on the surface of the plated part is controllable in thickness and hardness; and the obtained clad layer is bright, dense and good in adhesive force and comprehensive performance, and therefore the stability of the quality of products of all batches is guaranteed, and the problem that in the prior art, the thickness of a coating is hard to control,and the product batch quality is unstable is relieved. The clad layer is further provided and is manufactured through the brushing electroplating process method, and the clad layer is smooth, bright,dense, good in adhesive force, controllable in thickness and hardness and good in comprehensive quality.

Description

technical field [0001] The invention relates to the technical field of brush plating, in particular to a brush plating process method, coating and application. Background technique [0002] Since the 1980s, brush plating technology has been shown in equipment maintenance due to a series of advantages such as convenient use, easy operation, various types of plating solutions, high coating quality, fast deposition speed, low environmental pollution, and water and electricity saving. With strong vitality, it has been widely used in equipment maintenance in industrial and mining enterprises, and has solved the maintenance problems of large, expensive and imported equipment in many national key projects. Since brush plating involves many fields, the problems to be solved are different. Therefore, the development and use of various plating solutions are targeted. There are also many. After trial, it is found that the thickness of the coating is difficult to control, the quality o...
