Research on Friction Property of the Ni/ZrO₂ Composite Infiltrated Layer on Cast Steel Surface under High Temperature

Abstract:

The surface composite layer Ni/ZrO₂ on the ZG45 cast steel surface was fabricated through vacuum infiltration casting method. This paper researched on the Ni/ZrO₂ composite infiltrated layer morphology, hardness and the friction property under fry friction. The results show that the added of the ZrO₂ ceramic particles increase the composite infiltrated layer hardness and the wear resistance. The 15% ZrO₂composite infiltrated layer wear resistance is better than the 10% ZrO₂composite infiltrated layer. Different ZrO₂contents have same change trend. The friction coefficient decreases with the temperature increasing. The 10% ZrO₂friction coefficient changes obviously with the temperature increasing. The 15% ZrO₂friction coefficient changes evener than the 10% ZrO₂ but the protection of friction and wear is more obvious.
