Research and Application of High-temperature Anti-oxidation Coatings for Titanium Alloys

Titanium alloys are widely used in aerospace, chemical engineering and other fields due to their excellent mechanical properties. However, in high-temperature environments, titanium alloys are prone to react with oxygen to form oxides, thereby affecting their performance. To solve this problem, scientists have developed high-temperature anti-oxidation coatings for titanium alloys.

I. The Principle of High-temperature Anti-oxidation Coating for Titanium Alloys
The principle of high-temperature anti-oxidation coating for titanium alloys is to form a dense oxide film on the surface of titanium alloys, preventing oxygen from coming into direct contact with the titanium alloy substrate. This oxide film has high-temperature stability and can effectively protect titanium alloys from oxidation.
