Paper Title:
Effect of CeO2 on Microstructure and Properties of WC/Ni60 Coating by Laser Cladding
  Abstract

The composite coatings of self-flux alloy matrix reinforced by WC-12%Co were produced on the surface of 45 steel using laser cladding technology. The effects of CeO2 to macro-morphology, microstructure, hardness, wear resistance and corrosion resistance of cladding layer were investigated. The results show that rare earths oxide (CeO2) added laser cladding coating has distribution, dimension phases and less deficiency. CeO2 could promote liquating process of WC, increasing the quantity and distribute uniformity of intermetallic compounds in laser cladding layer. Because of dispersion precipitation and fine-crystal strengthen effect, laser cladding layer with CeO2 has higher microhardness, wearing resistance and better corrosion resistance properties.
