摘要
利用超音速火焰喷涂工艺在316不锈钢基体上制备铁基非晶态合金涂层,研究了涂层的磨削性能、涂层磨削表面的耐磨性能和耐腐蚀性能。结果表明,3个磨削参数中,磨削深度对涂层表面的表面粗糙度及耐腐蚀性能影响最大,进给速度次之;而进给速度对涂层表面耐磨性能影响最大,磨削深度次之;磨削速度对涂层的表面粗糙度、耐磨性能和耐腐蚀性能影响较小。最后,根据不同的涂层性能要求对磨削参数组合进行优化。
Fe-based amorphous alloy coatings were prepared by high velocity oxygen fuel（HVOF） thermal spraying on 316 stainless steel substrate. The grinding performance, the wear resistance and the corrosion resistance of the ground surface for the Fe-based amorphous alloy coatings was explored. The results show that the grinding depth influences the surface roughness and corrosion resistance of the coatings＇ surface the most, and the feed speed takes the second place. The feed speed influences the wear resistance of the coatings＇ surface the most, and the grinding depth takes the second place. Besides, the grinding speeding has the minimal impact on surface roughness, the wear resistance and the corrosion resistance of the coatings＇ surface. Finally, the best grinding parameter combination was selected according to the different characteristics of coatings.
