主 题:Copper pipe plasma cladding WC Ni60A microstructure high-temperature wear behaviour
摘 要:With the aim of improving the surface properties of copper, WC/Ni60A composite coatings were successfully prepared by plasma cladding. A good metallurgical bonding was formed between composite coating and copper substrate. The large amount of dispersed WC and W2C phases in the coating significantly increased the microhardness (17 times that of the copper substrate). With the rise in temperature, the wear resistance of the coating first increased and then decreased. At 400 degrees C, the coating had the best wear resistance due to the lubricating effect of the oxide layer. However, due to the simultaneous occurrence of various wear mechanisms, the wear resistance at 600 degrees C was significantly reduced, so the service temperature must be controlled below 600 degrees C.
