Al2O3/TiCN-0.2％Y2O3 Composite Prepared by HP and Its Cutting Performance

摘要：

Al2O3/TiCN-0.2％ Y2O3 composites were fabricated by hot pressing sintering. The effect on mechanical property and microstructure of the sample composition and HP temperate was investigated. The results of Al2O3/TiCN-0.2％ Y2O3 were satisfied. The bending strength, fracture toughness, Vickers hardness was respectively 1015 Mpa, 6.89 Mpa· m1/2, 20.82 Mpa at 1650 ℃ for 20 min. Good wear resistance was found for the kind of ceramic material when used as cutting tools in the machining of the hardened carbon steel. By the compared experiment for the cutting performances, it could be seen that the performance of this composite material was better than that of the ceramic tool material YT15 for continuously cutting quenched steel. This kind of composite tool material is suitable for continuously cutting quenched steel No. 45, especially intermittently cutting quenched steel.
