Wear-resistant coating film, wear-resistant member, method of making wear-resistant coating film, and sliding mechanism

摘要

The present invention provides a wear-resistant coating film which can maintain high wear resistance for a long period of time even when subjected to repeated wear and tear, and a method of making the film as well as a wear-resistant component. The wear-resistant coating film 10 of the present invention has a metallized layer 11, lump parts 2, and a coating layer 13. The metallized layer 11 and the coating layer 13 are laminated in this order, and each of the lump parts 2 is formed from a single particle 12 and / or an array of particles 12. The lump parts 2 are held by the metallized layer 11 and are arranged so as to protrude from the metallized layer 11. The coating layer 13 is formed to coat the surface of the metallized layer 11, the lump parts 2 have flat portions 18, and the flat portions 18 are arranged on the same plane as the surface of the coating layer 13.
