Embodiment Construction

[0014] The technical solutions of the present invention are described below through specific examples, and the following examples are only for illustrating the present invention rather than limiting the scope of the present invention.

[0015] A method for electroplating aluminum alloy, comprising a degreasing part, an electrolytic etching part and an electroplating part;

[0016] The degreasing part includes degreasing and washing, and is used to remove the grease on the surface of the plated parts; the degreasing in this application is an existing technology, and it is not necessary to carry out the acidic or alkaline grease removal technology at the same time, which has been It is a public technology, and will not be described in detail here.

[0017] The electrolytic etching part includes anodic electrolytic etching and bizincate conversion etching;

[0018] The electroplating part is electroplating with sulfamate as electrolyte.

[0019] In the electrolytic etching part...

Abstract

The invention relates to a method for electroplating aluminium alloy, which comprise steps of a degreasing part, an electrolysis etching part and an electroplating part, wherein the degreasing part comprises steps of degreasing and washing so as to remove grease on the surface of a to-be-plated piece; the electrolysis etching part comprises steps of anode electrolysis etching and heavy zincate conversion etching; and the electroplating part takes sulfamate as electrolyte for electroplating.

Description

technical field [0001] The invention belongs to the field of metal electroplating, in particular to a method for electroplating aluminum alloy containing silicon. Background technique [0002] The current conventional method of electroplating aluminum alloy is the heavy zincate method, which involves as many as 15 processes. Therefore, the unqualified rate has always been high, and the use of substances harmful to the human body and the environment in the electroplating process cannot reach The requirements of various countries for environmental protection. [0003] In order to improve the above-mentioned method, the prior art has proposed a multi-component conversion method using iron, copper and nickel, etc., also known as the anode conversion method. This method is the same as the heavy zincate cocaine method, and the operations are reduced to some extent. However, the bonding force of the plating layer of this method to the surface of the aluminum alloy is not high. In...
