Wear Resistance of Cu10Al5Fe5Ni Alloy

摘要

The effect of ambient temperature, materials state and lubrication condition on wear resistance of Cu10Al5Fe5Ni alloy was investigated. The wear surface morphology was characterized by a scanning electron microscope (SEM), and the wear mechanism was discussed as well. The results show that the friction coefficient of Cu10A15Fe5Ni alloy increases and then decreases with increasing temperature. The wear rate of the Cu10A15Fe5Ni alloy after solid solution and ageing treatment is less than that of the as-cast alloy, and the wear rate of Cu10A15Fe5Ni alloy reduces dramatically from 5.31×10~(-5) mm~3 / (nv N) into 1.80×10~(-6) mm~3 / (m·N) after adding lubricating oil. At elevated temperature, the prior wear mechanism is the fatigue wear, accompanying by slight abrasive wear and adhesive wear for the aged Cu10A15Fe5Ni alloy.
