摘要/Abstract

摘要： 材料表面应力状态对材料的冲蚀磨损行为起着重要作用。本文利用有限元方法探讨了冲蚀角度、冲蚀速度、磨料粒径对微晶玻璃涂层冲蚀应力的影响,利用常温冲蚀试验机对微晶玻璃涂层在不同冲蚀角度下的体积磨损率进行了测定。结果表明,随冲蚀角度、冲蚀速度、磨料粒径增大,涂层的冲蚀应力均逐渐增大。在相同的冲蚀角度和冲蚀速度条件下,磨料粒径对涂层冲蚀应力的提升效果显著。微晶玻璃涂层冲蚀磨损率随冲蚀角度的增大而增加,其变化规律与冲蚀应力变化趋势基本一致,从而验证了有限元应力模拟的可靠性。

Abstract: The stress state on the surface of material plays an important role on the erosion wear behavior of material. In this paper, the effects of erosion angle, erosion velocity and abrasive particle size on the erosion stress of glass-ceramic coating were discussed by finite element method.The volume wear rate of glass-ceramic coating under different erosion angle was measured by erosion tester at room temperature.The results show that the erosion stress of glass-ceramic coating increases with the increase of erosion angle, erosion velocity and abrasive particle size. Under the same erosion angle and erosion velocity, the effect of abrasive particle size on the improvement of coating erosion stress is significant. The erosion wear rate of glass-ceramic coating increases with the increase of erosion angle, and its change trend is basically consistent with the change trend of erosion stress, which verifies the reliability of finite element stress simulation.

Key words: glass-ceramic coating, erosion wear, finite element simulation, stress distribution, erosion angle, erosion velocity, abrasive particle size
