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 main phase structure of the layer is ZrO2, Cr2B, NiB and FeNi. The macrohardness of the layer is HRC60~64. The micohardness presents gradient change. The maximum hardness appears at subsuface. The 10% ZrO2 composite infiltrated layer wear resistance increases 10 times and 15% ZrO2 composite infiltrated layer increases 22.6 times than ZG45 under the 100N load. The 10% ZrO2 composite infiltrated layer wear resistance increases 8.5 times and 15% ZrO2 composite infiltrated layer increases 21.9 times under 250N load. The wear resistance has greatly improved.
