单颗粒金刚石划擦工程陶瓷的断裂强度研究
Research on scratching fracture strength with single diamond for engineering ceramics
摘要
Abstract
To reveal the inherent laws between single abrasive particle of diamond wheel and fracture strength of engineering ceramics during the grinding,a special single diamond tool was introduced to substitute the actual wheel. With the diamond abrasive of diverse apex angles and tip radius, different scratching parameters and cooling condition were set before the surface scratching upon several types of engineering ceramics. Then,relationships on the experimental parameters and fracture strength were intensively investigated. The results show that the fracture strength of scratched ceramics increase with the rise of apex angle and tip radius of abrasive, reduce with the addition of feed rate and scratching depth. Besides, the fracture strength after wet scratching is always better than that of dry scratching. The findings accord with relevant patterns and mechanisms in grinding machining, which also verify the significance of single diamond scratching test.关键词
