Abstract

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.

Abstract

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.

Abstract

Disclosed herein is a method comprising: spraying a coating onto a surface of a component, wherein the coating is at least partially amorphous, wherein the coating is configured to protect the component for underground use. Disclosed herein is a component so coated. The coating may have an elastic strain limit greater than a yield strain of the component. The coating may have a modulus of elasticity lower than a modulus of elasticity of the component. The coating may have a hardness higher than a hardness of the surface. A coefficient of friction between the coating and steel may be lower than a coefficient of friction between steel and steel.
