Abrégé

Provided is a method for increasing anti-galling of parts using a coating material comprising an amorphous alloy. The parts may be a vehicle or machine component, for example, that are subject to frictional and sliding forces. The disclosed coating reduces galling and friction between surfaces, and increases the lift of such parts.

Abrégé

The present invention relates to a thermal-spray coating composition which has a lower friction coefficient and higher abrasion resistance than thermal-spray coating compositions of molybdenum (Mo) or using molybdenum (Mo) as a major constituent that have conventionally been widely used in abrasion-resistance applications where a low friction coefficient is required, and which is able to extend the life of a part compared with said thermal-spray coating compositions of molybdenum (Mo) or using molybdenum (Mo) as a major constituent.
