摘要
综述了有关增韧陶瓷的准静态、弹塑性、点坑及屑片和速度坐标系冲蚀模型及其刀学分析。讨论了靶材韧性与硬度、冲蚀速度与冲蚀角、显微组织及相变增韧行为对冲蚀的影响规律的最新研究成果。对比分析了增韧陶瓷和传统陶瓷及金属材料的冲蚀规律的异同之处。
Erosion models,such as quasi-static,elasticplastic,pitting,chipping,and velocity coordinates system model,are surveyed in this paper. The effects of target toughness, impingement velocity and angle, microstructure and transformation toughening on erosion are disccussed also. The erosion behaviors of toughened ceramics,conventional silicate ceramics and metallic materials are compared
