Research Progress on WC Composite Coating Preparation Technique and Performance of Wear Resistance and Corrosion Resistance
Tungsten carbide coatings have the characteristics of high chemical stability,high hardness,and good wear resistance,and are commonly used in the preparation of metal surface coatings.Starting from the different preparation principles of tungsten carbide coatings,the research progress of supersonic flame spraying technology,plasma spraying,plasma melting,laser melting,and vacuum melting tungsten carbide coatings at home and abroad were reviewed.The wear resistance and corrosion resistance of the coatings with different preparation technologies were analyzed,and the problems and future research directions of coating preparation technology were discussed.
