Titanium-aluminum composite material surface porous treatment agent, treatment method and application of titanium-aluminum composite material surface porous treatment agent

Abstract

According to the present invention, the titanium aluminum composite material surface porous treatment agent is provided, the treatment agent comprises hydrogen peroxide and an acid, and the acid comprises PO4 < 3-> ions and / or SO4 < 2-> ions, and does not comprise halide ions. The invention further provides a treatment method for carrying out porosity on the surface of the titanium-aluminum composite material by using the treatment agent, the titanium-aluminum composite material is put into an oxidation tank electrolyte containing the treatment agent to be subjected to electrochemical anodic oxidation treatment, and then regular and ordered nano-pore oxidation layers can be formed on the titanium-based surface and the aluminum-based surface at the same time. Compared with a method in the prior art that the aluminum base needs to be subjected to oxidation hole sealing treatment firstly, and then the titanium base and the aluminum base of the titanium-aluminum composite material are subjected to porous treatment in two steps, the method is simple and efficient, the manufacturing cost is effectively reduced, and wide application value is brought to surface modification of the titanium-aluminum composite material.
