Research Status of WC-10Co4Cr Coatings Prepared by Thermal Spraying

The WC ceramic coatings were widely applied in many kinds of fields as resistant coatings owing to their high hardness and excellent wear resistance.Both union intensity of WC-10Co4Cr ceramic coatings,wear resistance and anti-corrosion performance are more favorable than the traditional WC coatings.This paper summarizes the methods and processes of WC-10Co4Cr coatings prepared by thermal spraying,and points out which are the most efficient methods for WC-10Co4Cr powders and coatings.The research achievements about WC-10Co4Cr of scholars are summarized in recent years.Through analyzing the influencing factors and mechanism for structures and properties of coatings,the author forecasts the development trend of WC-10Co4Cr coatings prepared by thermal spraying.
