一种抗高温氧化的晶须改性Ti(C,N)基复合金属陶瓷制备方法
摘要：
本发明公开了一种抗高温氧化的晶须改性Ti(C,N)基复合金属陶瓷制备方法，属于高速切削刀具材料领域。本发明的晶须改性Ti(C,N)基复合金属陶瓷制备方法，经过原料组配、球磨混料、烘料、真空热压烧结等步骤。本发明的晶须改性Ti(C,N)基复合金属陶瓷，其组分重量百分比为：Ti(C0.5N0.5):45～60％，Al2O3晶须或ZrO2晶须:10～25％，WC:8～15％，Co:5～10％，Mo2C:5～10％，Ni:5～10％。本发明制备出的Ti(C,N)基复合金属陶瓷，不仅具有良好的致密性，而且还具有高强韧性和抗高温氧化性，可作为特殊钢材的(半)精加工的切削刀具材料。
摘要（英）：

The invention discloses a preparation method of anti-high-temperature-oxidation crystal whisker modified Ti(C,N) base composite metal ceramic, and belongs to the field of high-speed cutter materials. The preparation method of the crystal whisker modified Ti(C,N) base composite metal ceramic comprises the steps of raw material matching, ball milling and material mixing, material drying, vacuum hot pressed sintering and the like. The crystal whisker modified Ti(C,N) base composite metal ceramic comprises, by weight, 45-60% of Ti(C<0.5>N<0.5>), 10-25% f Al2O3 crystal whisker or ZrO2 crystal whisker, 8-15% of WC, 5-10% of Co, 5-10% of Mo2C and 5-10% of Ni. The Ti(C,N) base composite metal ceramic obtained through the preparation method has excellent compactness, high-strength toughness and high temperature oxidation resistance, and can serve as a (semi) precision-machined cutter material of a special steel material.
