The recent rapid progress in surface treatment techniques dictates that titanium alloys should have an improved resistance to frictional wear without any loss of their high corrosion resistance. These requirements can be satisfied by producing surface layers of specified microstructure and phase composition. The paper presents the results of metallographical examinations, corrosion and wear resistance tests and SEM observations of the surface layers produced on the OT4-0 titanium alloy using the nitriding and carbonitriding process under glow discharge conditions. These techniques permit controlling the chemical composition, thickness and microstructure of the surface layers, parameters that essentially affect their performance properties such as the corrosion resistance and frictional wear resistance.
