산화크롬/몰리브덴 복합 플라즈마 용사 코팅의 마찰, 마모 특성 연구
A study on friction and wear properties of plasma-sprayed $Cr_2O_3/Mo$ composite coatings
초록
Plasma-sprayed coatings were obtained by spray-dried $Cr_2O_3$ powder with and without Mo addition. A reciprocal type tribo-tester was employed to examine friction and wear behavior of the specimens at room temperature. The composition and the worn surface of coated specimens were observed by XRD and SEM. The results showed that friction Coefficient of the Mo added specimens were lower than one of $Cr_2O_3$ specimen. But $Cr_2O_3$ specimen had a lower wear loss. Protecting layer were observed at the worn surface of coated specimens with Mo addition.
