摘要:
Wear resistant composite layers were fabricated on 38CrMoAl steel by laser processing with NiCr/Cr3C2-CeO2 powders with addition of MoS2 or WS2. The composite layers were heat treated at 150 and 300 degrees C (MoS2), and 3(X) and 600 degrees C (WS2). Microstructure, phases, microhardness, wear behaviour at room temperature and crack behaviour under loading of the laser processed and heat treated layers were investigated. Results indicate that undissolved MoS2 or WS2 were observed in all the laye ...More
