Abstract
The methods of laser surface engineering, including laser cladding, laser alloying from predeposited layers, and laser alloying from the gas phase have been applied to increase the wear resistance and decrease the coefficient of friction of metallic surfaces. Laser cladding has been applied to deposit metal matrix composites that consist of CuSn, stellite, stainless steel, and bronze, which act as solid lubricant reinforced with nanostructured WC ceramics with Co binding. Laser alloying of bearing steel with Sn increases the lifetime of oil turbo drills. Wear tests of Ti alloys doped with nitrogen from a gas atmosphere have demonstrated a viable possibility to apply the developed method to fabricate frictional couples.
