Abstract
Growth of coating layer and wear properties of chemically vapor deposited (CVD) TiC onto WC-Co substrate were investigated. The deposition temperature, time and Co content of the substrate showed pronounced effects on the thickness of coating layer. The texture of TiC layer changed from <100> orientation at low deposition temperature (950℃) to random orientation at high deposition temperature (1050℃). The wear resistance of coated specimen was remarkably increased and enhanced wear resistance was also discussed.
