Laser surface alloying of pure titanium with TiN–B–Si–Ni mixed powders

Laser alloying was carried out on the surface of pure titanium substrate with TiN–B–Si–Ni mixed powders. The result of X-ray diffraction (XRD) analysis shows that the alloyed layer consists of many kinds of intermetallic compounds. The test results show that the alloyed layers have high microhardnes...

Zusammenfassung:Laser alloying was carried out on the surface of pure titanium substrate with TiN–B–Si–Ni mixed powders. The result of X-ray diffraction (XRD) analysis shows that the alloyed layer consists of many kinds of intermetallic compounds. The test results show that the alloyed layers have high microhardness (1500–1600HV0.1), low friction coefficient (about 0.4), and are more resistant to oxidation than untreated substrate.
