Hot Pressing Sintering

Three ceramic composite were prepared by hot pressing sintering. The friction and wear behaviors of the composite were experimented at the high speed wear and tear test machine. Results show that the three ceramic composite have strong fracture toughness and flexure strength. The wear mechanisms of three ceramic composite are mainly brittleness peel off and furrow. Al2O3/(W, Ti)C and Al2O3/SiCw ceramic composite have great capabilities in wear resistance; they are excellent materials of cutting tools and dies.

Hot Pressing Sintering

In this work, two kinds of Al2O3-TiC-TiN ceramic cutting tools (AC2U and AC2UN2) were developed by hot-pressing sintering techniques. The mechanical properties were measured and the cutting performance was investigated. The workpiece used in the cutting experiment was quenched carbon tool steel T10A, and the tool material for comparison was LT55. The wear resistance and the main wear patterns of the ceramic tools were analyzed at the high speed of 300m/min. The results indicated that the novel Al2O3-TiC-TiN ceramic cutting tools showed better cutting performance than LT55, and AC2UN2 was better suitable for machining quenched T10A. When the cutting condition was v=300m/min, f=0.1mm/r and ap=0.1mm, the adhesion wear and abrasive wear of the novel ceramic tools were slighter than those of LT55, the diffusion wear resistance of AC2U was better and the oxidation resistance of AC2UN2 was better.

The effect of Y-TZP additive on the mechanical properties of Al2O3-TiB2 ceramics was investigated. The results indicate that Y-TZP additive can enhance the flexure strength and fracture toughness of Al2O3-TiB2 ceramics, but has little effect on their hardness. The maximum bending strength of Al2O3-TiB2 and Al2O3-TiB2-Y-TZP ceramics are at 20vol% TiB2 content. The maximum fracture toughness for two kinds of ceramics all are at 30vol% TiB2 content. The bending strength and fracture toughness as well as impact resistance of Al2O3-TiB2-Y-TZP ceramics are higher than those of Al2O3-TiB2 ceramics. The cutting behaviors of two kinds of ceramics are satisfactory. When the ceramic cutting tools are applied to continuous cutting, the wear resistance of cutting tools increases as an increase in TiB2 content. But when they are applied to intermittent cutting, the serving life of ceramic cutting tools is mainly governed by their fracture toughness, The mainly failure mechanism of intermittent cutting is micro-chipping.
