Titanium alloys have been widely used in aviation, aerospace, medical and other fields due to their excellent mechanical properties, corrosion resistance and biocompatibility. However, the surface properties of titanium alloys have a decisive influence on their performance, so it is very important to surface treat titanium alloy parts. The following are several common titanium alloy surface treatment methods:

Mechanical treatment:

Polishing: Mechanical polishing can improve the surface finish of titanium alloy parts, reduce surface roughness and improve appearance quality.

Grinding: Use abrasives to grind the surface of titanium alloys to remove oxide layers and processing marks.

Chemical treatment:

Pickling: Use acid solution to remove oxides and contaminants on the surface and improve surface cleanliness.

Alkali washing: Remove grease and other organic contaminants to prepare for subsequent treatment.

Anodizing:
A layer of titanium oxide film is formed on the surface of titanium alloy by electrolysis. This film can improve corrosion resistance and hardness, and can also give parts different colors.

Micro-arc oxidation (MAO):

Micro-arc oxidation is a surface treatment technology performed at a higher voltage, which can form a dense ceramic oxide film on the surface of titanium alloy. This film has high hardness and good wear resistance.

Electroplating:
Electroplastication of other metals or alloys, such as chromium and nickel, on the surface of titanium alloy can improve its wear resistance and corrosion resistance, but the bonding strength between the coating and the substrate is a problem that needs to be solved.
Laser treatment:
Using high-energy laser beams to remelt or alloy the surface of titanium alloy, a surface layer with special properties can be obtained.
Coating technology:
Technologies such as physical vapor deposition (PVD) and chemical vapor deposition (CVD) are used to coat a protective film on the surface of titanium alloy, which can be a ceramic coating or a metal coating, to improve wear resistance, corrosion resistance, etc.
When performing surface treatment of titanium alloy, the following points should be noted:
Titanium alloy is highly active and easily reacts with certain elements such as oxygen and nitrogen, so the process parameters should be strictly controlled during the treatment process.
Surface treatment should ensure that the performance of the titanium alloy substrate is not damaged.
The treated surface should meet the requirements of the specific application environment, such as corrosion resistance, wear resistance, fatigue performance, etc.
According to different application requirements, a suitable surface treatment method or a combination thereof can be selected to achieve the best use effect.
