Wear Resistant of Al_2O_3/Heat-Resistant Steel at High Temperature

摘要

The high temperature abrasive wear resistant of the composites with different Al_2O_3 volume fractions, particle coating and size were investigated and the failure action of composites under different conditions at high temperature was analyzed. The results showed that the high temperature abrasive wear resistant of composite with Ni coating and wide size and 39% volume fraction of particle is the best among all composites examined.
