Preparation method of WC-Co wear-resistant self-lubricating coating

The invention relates to the technical field of coating preparation, in particular to a preparation method of a WC-Co wear-resistant self-lubricating coating, the WC-Co wear-resistant self-lubricating coating is prepared through thermal spraying-vulcanization composite treatment, the high-hardness coating is prepared on the surface of a base material through the thermal spraying technology, but the wear resistance of the coating cannot be obviously improved, and the coating cannot be subjected to high-hardness coating treatment. However, the friction coefficient of the coating can be reduced, the self-lubricating property and the thermal stability of the coating can be improved and the wear resistance of the coating can be improved after the spraying state coating is subjected to vulcanization treatment, and the preparation method can reduce the requirement for a traditional lubricant, reduce the lubricating cost and the environmental influence, prolong the service life of equipment and reduce the shutdown ma
