Study on Microstructure and Tribological Properties of Plasma Nitriding Modified Layer on 1050 Al Surface
The nitrided layer was formed on the surface of 1050 Al alloy by plasma nitriding.The surface composition,phase structure and morphology of the nitrided alloy were characterized.Dry sliding properties of the nitride layer was in vestigated by reciprocating sliding wear test.The results indicate that the nitrided layer is mainly composed of AlN and Al.The friction coefficient of the nitrided layer is significantly lower than the substrate,and the wear resistance of the alloy increases.
