Research progress in surface strengthening technology of carbide-based coating

The carbide phase in the coating can enhance the wear resistance, corrosion resistance, heat resistance, and oxidation resistance of the coating. Because the carbide-based coating can increase the service life of metal parts and further upgrade the performance of the substrate, it has been extensively studied by a large number of scientists. The carbide-based coating is widely used as a common surface strengthening technology to improve the substrate. Although a series of achievements have been made, few reviews have been made on improving the properties of carbides-based coatings. In this paper, a series of methods to improve the properties of carbides-based coatings are systematically introduced. In the first part, the necessity of studying carbide-based coatings under the current social development trend is introduced. In the second part, the common carbide coatings are introduced. In the third part, some forms of failure of carbide-based coatings are introduced. In the fourth part, a series of measures to better the performance of carbide coating are put forward. The last is a summary of the carbide coating and the prospect of future development. 0 2022 Published by Elsevier B.V.
