Abstract
The invention relates to a surface treatment method of a silicon carbide and metal composite material. The surface treatment method comprises the steps of pretreatment, anodizing, surface metallization and blackening, wherein the pretreatment includes deoiling, alkaline etching and polishing to obtain the clean surface of the silicon carbide and metal composite material; the anodizing comprises the steps of carrying out anodic oxidation on an anode which is the silicon carbide and metal composite material and a cathode which is a lead plate or an aluminum plate in anodizing solution to obtain an oxidation film on the surface of the composite material; the surface metallization refers to the steps of sensitization, activation, reduction or chemical plating to obtain a surface conductive layer; and the blacking treatment includes black nickel plating or black chrome electroplating, therefore, a finished product is obtained. According to the surface treatment method, the adhesion force of the black layer is good, the technological quality is stable, the cost is low and an environment-friendly effect is achieved.
Description
Metal field
The present invention relates to process for treating surface, particularly relate to a kind of silicon carbide and metal composite surface treatment method.
Background technology
Silicon carbide and metal composite, except having the premium properties of ordinary skill, also there is superelevation strong hardness, hot dimensional stabilizing, be widely used, need to be to this material surface blackening process in a lot of occasions, control reflection of light degree, general requirement surface blackening is not less than 90%, and black coating its black layer bonding force in common metal surface is poor, and silicon carbide conduction is poor on the other hand, do not plate blackout metal, can affect entirety blackout effect.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of black layer bonding force good, and processing quality is stable, and cost is low, the silicon carbide of environmental protection and metal composite surface treatment method.
The technical scheme adopting is:
A kind of silicon carbide and metal composite surface treatment method, comprise the following steps:
(1) pre-treatment, adopts oil removing, alkaline etching, finishing method, obtains clean silicon carbide and metal composite surface;
(2) anodizing, is to be anode by the silicon carbide after pre-treatment and metal composite, and stereotype or aluminium sheet are negative electrode, carry out anodic oxidation in anodic oxidation solution, obtain composite material surface oxide film;
(3) surface metalation, adopts sensitization, activation, reduction or chemical plating method to obtain surperficial conductive layer;
(4) blackening process, adopts black coating nickel or black chromium electro-plating method.
The black layer of the present invention bonding force is good, and processing quality is stable, and cost is low, environmental protection.
