Abstract
A bulk amorphous NiTiZrSiSn produced using an inert gas atomization was sprayed onto the Cu substrate. As the oxygen to hydrogen gas fraction was increased, oxide phase fraction was increased at the expenditure of amorphous phase fraction. The phase evolution was mainly due to the in-flight particle oxidation according to flame gas composition. Tribological behaviors were investigated in view of friction coefficient and weight loss by a pin-on-disc dry sliding test. Both friction coefficient and weight loss were largely dependent on the phase composition of the coating. As the amorphous phase fraction was increased, the friction coefficient was decreased with the increase of the transfer film formation. On the other hands, major weight loss mechanism was changed from transfer film formation to pull-out of coat material as the amorphous phase fraction was decreased.
