摘要

针对工程陶瓷的崩碎损伤

应用单颗粒划痕实验系统研究了切向载荷作用下Si

陶瓷的崩碎损伤特征和机理。比较了损伤位置、切入深度、切向速度和金刚石磨粒磨损等因素对陶瓷崩碎损伤的影响

应用3D激光测量显微镜观测了崩碎损伤表面的三维形貌

应用扫描电镜分析了崩碎损伤机理。结果表明:出口崩碎损伤是陶瓷崩碎损伤的主要形式;切入深度越大

切向速度越小

金刚石颗粒磨损越多

崩碎损伤就越严重。出口崩碎损伤的中心剖面线具有显著的阶梯形分形特征

其扩展演化规律可由逾渗理论和裂纹扩展的最小阻力原理解释。在切向载荷作用下

入口崩碎损伤在金刚石磨粒的碰撞下主要以穿晶断裂为主;内部崩碎损伤在金刚石磨粒的挤压和切割下主要以破碎和铲除的形式发生断裂;而出口崩碎损伤主要以沿晶断裂为主。

Abstract

A single diamond grit scratching test system was built to explore the damage mechanism and the edge chipping characteristics of Si

ceramics. The effects of damage stations

cutting depths

cutting velocities and grit wears on the edge chipping of the Si

ceramic were compared. A 3D laser measurement microscope was used to observe the geometric morphology of edge chipping and the Scanning Electric Microscopy (SEM) was taken to analyze the damage mechanisms of edge chipping. The results show that exit edge chipping is the main damage for ceramics. The cutting depths

cutting velocities and grit wears would affect the edge chipping obviously. The medical section curve of exit edge chipping has obvious staircase fractal characteristics

which could be explained well by percolation theory and the crack propagation principle of least resistance. The damage mechanism for entry edge chipping is mainly transgranular fracture

the damage mechanical for exit edge chipping is mainly intergranular fracture

and the interior edge chipping is engendered by eradicating and cutting.
