用相同的喷砂和喷涂工艺参数，分别在４５~＃钢基体上制备了电弧喷涂与高速电弧喷涂ＦｅＣｒＡｌ涂层，用扫描电镜分析了它们的表面形貌，测试分析了两种涂层及各自基体在距涂层－基体界面不同距离上的显微硬度值；得到了电弧喷涂及高速电弧喷涂基体上的热影响区宽度，讨论了涂层的显微组织对其硬度的影响；并测试分析了涂层和基体的截面线波动系数。试验结果表明，高速电弧喷涂ＦｅＣｒＡｌ涂层比普通电弧喷涂ＦｅＣｒＡｌ涂层具有更好的微观性能。
Arc spraying and high speed arc spraying of FeCrAl coatings were prepared on 45 ~ # steel substrates with the same blasting and spraying process parameters respectively. Their surface topography was analyzed by scanning electron microscopy. Two coatings and their coatings The microhardness values of the substrate at different distances from the coating-substrate interface were obtained. The width of the heat-affected zone on the substrate was obtained by arc spraying and high-speed arc spraying. The influence of the microstructure of the coating on the hardness was also discussed. The cross-sectional line-to-line coefficient of the coating and substrate. The experimental results show that the high speed arc spraying FeCrAl coating has better micro-performance than the ordinary arc spraying FeCrAl coating.
