Al2O3/Ti(C,N) composite ceramic tool material and microwave sintering process thereof
The invention discloses an Al2O3/Ti(C,N) composite ceramic tool material and a microwave sintering process thereof. The Al2O3/Ti(C,N) composite ceramic tool material is prepared from, by mass, 61%-70% of alumina (Al2O3), 25%-35% of titanium carbonitride (Ti(C,N)), 2%-6% of nickel (Ni) and 1%-3% of molybdenum (Mo). Ceramic tool materials are sintered in a microwave sintering furnace with nitrogen as protection atmosphere through the characteristics that whole microwaves can conduct non-gradient heating, material compactness is promoted and environment friendliness is achieved, wherein the frequency of the microwave sintering furnace is 2.45 GHz. The prepared tool material is uniform in microstructure and small in crystalline grain, has high density, high fracture toughness and high harness, and the performance of the prepared tool material meets the use requirement of tools; meanwhile, the sintering process is advanced, the production efficiency is high, cost is low, large-scale production can be easily conducted, and popularization value is achieved.
