摘要:
To solve the serious wear problem of mold steels at a high temperature, a 15 wt% WCp (Tungsten Carbide particles) reinforced Fe 50 Mn 30 Cr 10 Co 10 HEA (High Entropy Alloy) composite coating is fabricated by laser cladding to improve the high-temperature wear resistance based on high hardness and thermal stability of HEA. Tribological tests are carried out at different temperature, and the wear mechanism is explored. The experimental results reveal three main phases of γ-Fe, WC, and W 2 C in the LCed (Laser Cladded) HEA composite coating. Sma...
