Fabrication and Characterization of Ceramic/Metal Composite Wear Preventive Coating

摘要：

　　The air plasma spray (APS) technology was used to prepare WC/NiCrAl and WC/NiCrBSi ceramic/metal composite wear preventive coating on cast iron substrate.The microstructure,microhardness,bond strength and slurry wear preventive performance of coating was measured.The results revealed that all of the coating prepared by APS has good qualities.The coating with NiCrBSi as its combining metal is better than that with NiCrAl on wear preventive performance,and coating containing more WC is supreme than that containing less WC.Finally,wear mechanics and the principle of the coatings wear preventive property was concluded.
