In this study, gradient WCX ceramic particle-reinforced W-Cu composites were successfully fabricated. The effects of carburization time on the microstructure, hardness, compressive strength, wear resistance, and electrical conductivity were investigated in detail. The results showed that the WCX gradient microstructure significantly improved the mechanical properties of the W-Cu composites and ensured their electrical conductivity.
In this study, gradient WCX ceramic particle-reinforced W-Cu composites were successfully fabricated by vacuum pulse carburization and an infiltration sintering process. The effects of carburization time on the microstructure, hardness, compressive strength, wear resistance, and electrical conductivity were investigated in detail. With an increase in carburization time, the edges of the W particles became coarse until a large number of cracked structures appeared. The WC phase and a small amount of the W2C phase were the primary carbides generated upon carburization for 60 to 100 min. The WCX gradient microstructure significantly improved the mechanical properties of the W-Cu composites. The gradient structure also ensured the electrical conductivity of the W-Cu composites.
