现在使用的纯氧化铝陶瓷刀具,虽在高温下能保持一定的硬度和强度,但太脆、抗热冲击性及耐磨性也不理想。为此,我们先后研制了三类、多种牌号的热压陶瓷刀具。试验证明:切削性能优良,在提高硬度、降低脆性方面有了很大的改进。现将我们研制的热压陶瓷刀具材料作一简介。一、陶瓷材料分类我们研制的热压陶瓷刀具材料可分为三类: Now used pure alumina ceramic tool, although at high temperatures to maintain a certain degree of hardness and strength, but too brittle, thermal shock resistance and wear resistance is not ideal. To this end, we have developed three types, a variety of brands of hot ceramic knives. Tests show that: excellent cutting performance, in improving the hardness, reduce brittleness has been greatly improved. Now we developed a hot ceramic tool material for a brief introduction. First, the classification of ceramic materials We developed the hot ceramic cutting tool materials can be divided into three categories:
