Notes:
Surface modification is a promising technique to improve wear properties of titanium andtitanium alloys by modifying either the surface composition or microstructure. Laser remelting andlaser nitriding of commercial purity titanium were carried out under pure argon and pure nitrogenambient, respectively. Characterization of the laser treated surface was done by optical microscopy,scanning electron microscopy (SEM), X-ray diffraction (XRD), microhardness tester. During laserirradiation heating, Ti exhibits a height activity and combines with N in the atmosphere of purenitrogen forming TiN and TiN0.3, whereas Ti only transform into martensitic Ti in pure argon. TheVickers microhardnesses are greatly improved by laser remelting and laser nitriding
