摘要
运用直接压痕法、间接压痕法和切口梁法分别对四种陶瓷刀具材料进行断裂韧性的测试研究。对这三种方法所测得的结果进行了分析对比，从而得出直接压痕法是一种较为可靠的测试方法；并对这四种陶瓷刀具材料进行了评价。
The methods of direct indentation,indirect indentation and notched beam bending are used respectively to study the fracture toughness of four ceramic cutting tool materials.In this paper,the testing results of these methods are analysed.They show that the direct indentation method is a more reliable testing metho.For ceramic cutting tool materials are also evaluated.
