Typically, titanium does not have good seizure toughness. In general, a surface treatment must be applied if the component is subjected to sliding contact. Various surface treatments, including ion plating, plasma spray, metal plating, etc., are used to increase seizure resistance. This report details a surface modification process using a low cost interstitial element (oxygen) in a standard atmosphere furnace as the surface diffusion element. We investigated changes in the microstructure and mechanical properties in the vicinity of the surface and sliding properties. As a result, we were able to improve seizure resistance by effectively using oxygen for surface modification.
