Paper Title:
The Research on Wear Performance at Elevated Temperature of Ni-Based Infiltrated Layer
  Abstract

The Ni-based alloy was used as raw materials to fabricate the surface infiltrated layer with 1-4mm thickness on cast steel substrate through vacuum infiltrated casting technology. The microstructure indicate that the infiltrated layer included surface melting and sintering layer, metallurgical fusion layer and diffusion layer. Wear property was investigated under different temperature conditions such as room temperature, 150°C, 300°C and 450°C. The results indicated that the abrasion volume of infiltrated layer was near to third of that of substrate, and it was nearly half of the substrate. This illuminated that the infiltrated had excellent wearable property. The adherence and fatigue abrasion was the main wear mechanism under low temperature. Oxidation abrasion and adherence dominated the wearing process under elevated temperature.
