A brush-plating method for pretreatment of the inner wall of the whole tube of the target material bound by the rotating target of the long tube

Abstract

The invention discloses a pre-treatment brush plating method for an inner wall of a whole pipe of a long pipe rotating target bonded target material. The method comprises the following steps: a, a pre-treatment pre-step; b, a fixing step of the whole pipe of the target material; c, an electric brush plating step of the whole pipe of the target material; d, an electric brush plating post-treatmentstep and e, a metalizing step. The inner wall of the whole pipe of the target material of the long pipe rotating target is brush-plated by an enhancing metal layer uniformly effectively by way of electric brush plating, so that enough wettability between metal solder and the whole pipe of the target material is bonded, and the bonding effect of the long pipe rotating target are ensured and enhanced. During electric brush plating, anode connecting parts are arranged at a set distance of the whole pipe of the target material and the distances between anodes and cathodes in electric brush platingare shortened, so that the current density is kept moderately, the current density is uniform, the conducing effect is good, and the efficiency of the enhancing metal layer formed by electric brush plating is improved.

Description

technical field [0001] The invention relates to the technical field of pretreatment of rotating target binding, in particular to a brush-plating method for pretreatment of the inner wall of a long tube rotating target binding target. Background technique [0002] The pretreatment effect on the back tube of the rotating target and the whole target tube before binding directly affects the bonding firmness and welding rate of the rotating target binding. The low bonding firmness and welding rate make the rotating target in use Poor conduction, uneven heat dissipation, and easy to fall off occur when the target is used, which seriously affects the use of the product. Therefore, the pretreatment before the binding of the rotating target is particularly important. [0003] In order to precisely control the structure of the whole target tube, the inner wall of the target tube is processed by drilling, boring and other processes to process the size and shape of the inner circle, but...

AI Technical Summary

Problems solved by technology

In the existing brush-plating of the whole tube of the target material, there is only one cathode connection part, because the length of the whole tube of the target material is long, the distance between the brush plating head and the cathode connection part is too large during the brush-plating process, so that the target The current in the whole material tube is dispersed, and the conductive effect is uneven, so that the deposition rate of metal ions differs greatly during brush plating, resulting in high difficulty in operation, poor smoothness and uniformity of the formed reinforced metal layer, and low brush plating efficiency.
