Abstract FeCrNi/CBN cored wire is prepared by use of the pull-type flux cored wire machine (FCWM50 type), FeCrNi/CBN composite coating is made by high velocity arc spraying. The special properties of the composite coating can be improved by adding Cr, Ni and small amounts of rare earth elements to adjust the coating composition. The Tribological properties of FeCrNi/CBN composite coating with high velocity arc spraying is studied. Images and components and cross-section microstructure of coatings are analyzed by means of SEM, and EDS, etc. This research indicated that FeCrNi/CBN composite coatings have typical layered structure feature and high bond strength and hardness. Friction of coatings at near room temperature or higher has “Run-up” period. With the increase of temperature, friction coefficient of coatings becomes low and wearing capacity of coatings high. The adding of CBN powder highly improved the wearing capacity of coatings.

FeCrNi/CBN复合涂层高速电弧喷涂性能研究

摘要 FeCrNi/CBN药芯焊丝采用牵引式药芯焊丝机（FCWM50型）制备，FeCrNi/CBN复合镀层采用高速电弧喷涂。通过添加Cr、Ni和少量稀土元素来调整涂层成分，可以提高复合涂层的特殊性能。研究了高速电弧喷涂FeCrNi/CBN复合涂层的摩擦学性能。采用SEM、EDS等手段对涂层的图像、成分和截面微观结构进行分析。研究表明FeCrNi/CBN复合涂层具有典型的层状结构特征和较高的结合强度和硬度。涂层在接近室温或更高温度下的摩擦具有“磨合”期。随着温度的升高，涂层的摩擦系数变低，涂层的耐磨性高。CBN粉末的加入大大提高了涂层的耐磨性。
