Tribological Behavior of Thermally Sprayed Nano Composite Chromium Carbide

크로뮴 카바이드 나노 분말을 이용한 용사코팅 층의 내마모 특성에 관한 연구

Chromium carbides have the excellent wear properties as transition metal carbides. Their tribological applications were studied recently. The nano-sized ceramic could enhance the mechanical and electronical properties of materials. In this study, it was observed to test the wear of the coated surface of nano-sized chromium carbides. The nano-sized chromium carbides were produced by sol-gel processing. Coating surface of produced powders was obtained front plasma spraying. Wear test of coating surface was held increasing temperature. The friction coefficient and the wear loss were testified in dry environment. And the worn surfaces were analyzed by XRD and SEM.
