Microstructure and wear resistance of laser melted W/W_2Ni_3Si metal silicides matrix in situ composites

摘要

W/W_2Ni_3Si ternary metal suicide matrix in situ composites consisting of primary tungsten dendrites and the inter-dendritic W_2Ni_3Si ternary metal suicide were fabricated using a newly patented laser melting furnace. The W/W_2Ni_3Si in situ composites have excellent wear resistance under both room- and high-temperature sliding wear test conditions.
