Abstract

Nanostructured and ultra-fine WC-Co coatings were prepared by plasma spray. The friction and wear behavior at elevated temperature and failure mechanism were investigated. The results indicated that the sliding wear resistance of nanostructured coating is better than that of ultra-fine coating at high temperature. The wear mechanism is different between ultra-fine coating and nanostructured coating. Brittle fracture and adhesive wear dominate in ultra-fine coating followed with abrasive wear. Toughness fracture and abrasive wear dominate in nanostructured coating followed with adhesive wear.
