Tribological Properties of FeCrNi/CBN Composite Coating with Spraying High Velocity Arc

Abstract:

The Tribological properties of FeCrNi/CBN composite coating with spraying high velocity arc is studied. Images and components and cross-section microstructure of coatings are analyzed by the means of SEM, and EDS etc. This research indicates that FeCrNi/CBN composite coatings have typical layered structure characteristic and high bond strength and hardness. Friction coefficient of coatings at room and high temperatures have “Run-up” period. With the increase of temperature, friction coefficient of coatings becomes low and wearing capacity of coatings becomes high. The adding of CBN powder highly improved the wearing capacity of coatings.
