Quantitative relations were established between microstructure and wear resistance of highly alloyed materials, including high-Cr white irons and experimental Co-base and Ni-base powder metallurgy (PM) alloys now used or potentially to be used in coal mining, handling and gasification. The wear under study are low-stress abrasion, encountered in coal conversion and transfer applications, and gouging wear encountered in mining. The objective has two facets. On the practical side, the establishment of the optimum microstructures for wear resistance will allow design engineers to make more effective decisions regarding candidate alloys for coal-conversion processes. On the basic side, the establishment of a better understanding of the physical and mechanical metallurgy of wear will allow development of alloys with maximum wear resistance in a specific application with minimum alloy content.
