A surface plating method of titanium or titanium alloy and a plated member
By combining four-step pretreatment with stepped nickel plating and high-temperature heat treatment, a metallurgical bonding layer is formed, which solves the problem of poor adhesion of titanium and titanium alloy electroplating layers and achieves a strong bond and improved stability of the coating.

AI Technical Summary
The formation of a dense oxide film on the surface of titanium and titanium alloys in the air results in poor adhesion between the electroplated layer and the substrate, making it prone to peeling and flaking. The coating fails, especially under complex working conditions, which limits its application.
A four-step pretreatment process (degreasing, activation, micro-etching, and surface conditioning) combined with stepped nickel plating and high-temperature heat treatment is used to form a metallurgical bonding layer, ensuring a strong bond between the plating layer and the substrate.
It significantly improves coating adhesion, enhances coating quality and process stability, increases product reliability and service life, and can resist erosion and damage under complex working conditions.
