Title: ENHANCED CERMET WEAR-RESISTANT COMPOSITE MATERIAL AND METHOD FOR FABRICATION THEREOF
Abstract:
Provided are a cermet wear-resistant composite material and a method for fabrication thereof, the cermet composite material comprising the following components in parts by mass: 25-35 parts of nano-molybdenum carbide, 15-25 parts of nano-ceramic powder, 10-15 parts of glass fiber, 5-10 parts of cobalt, 10-15 parts of chromium, 10-15 parts of titanium carbonitride, 1-3 parts of zirconia, 3-5 parts of silicon oxide, 8-10 parts of cerium oxide, 1-3 parts of alumina, 5-10 parts of niobium carbide, 5-15 parts of silicon carbide, 1-3 parts of vanadium carbide, 4-9 parts of copper, 1-5 parts of titanium powder, 1-5 parts of coupling agent, 1-3 parts of antistatic agent, and 1-3 parts of curing agent. The method for fabricating the cermet composite material comprises: mixing, ball milling, drying, sintering, and cooling. The flexural strength of the cermet composite material may reach 2500 MPa and its Rockwell hardness may reach 93.
