Abstract

Vacuum plasma spraying has been used to fabricate dense MoSi2 and TiB2-reinforced MoSi2-based composites. The spray-formed deposits have high hardness and fracture toughness as compared to that achieved by other processing techniques. Annealing of the spray formed MoSi2 leads to a decrease in hardness and an increase in fracture toughness. Reinforcement with TiB2 leads to toughening and strengthening of the spray-formed MoSi2.
