METHOD OF POST HEAT-TREATMENT FOR THE IMPROVEMENT IN WEAR-RESISTANCE OF NANO-STRUCTURED WC-Co COATINGS

摘要

The invention nanostructured tungsten carbide-cobalt (WC-Co) 400 the total warrior coating in an inert atmosphere ~ 800 to 10 minutes at a temperature maintained in the after ronaeng ( ) by heat treatment in a manner that , the spraying process of the decarburization and a reduced material degradation due to carbide precipitation ( ) and such as to increase the coating bond provides a heat treatment method for improving the anti-wear properties of nanostructured WC-Co -based thermal spray coating over the effect .
