Abstract

Abstract An apparatus and method for thin film coating a substrate comprising spraying a stream of molybdenum disulfide powder mixed with steel shot at a predetermined velocity against the substrate, the velocity being sufficient, when impacting the substrate, to bond minute plate-like particles of molybdenum disulfide to the substrate and form a friction reducing surface thereon.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 118 words
The method of lubricant coating a substrate with a compound consisting of: (a) providing a quantity of molybdenum disulfide as a powder form dry lubricant; (b) providing a quantity of steel shot of predetermined mass; (c) commingling the molybdenum disulfide and steel shot to form a coating mix; (d) continuously agitating the coating mix; (e) maintaining a desired range of relative humidity surrounding the coating mix by heating air, surrounding the coating mix, to a temperature of approximately 20° F. above ambient temperature; and, (f) impacting a stream of the coating mix on the substrate at a predetermined velocity for a predetermined period of time for fusing and burnishing a portion of the dry lubricant on the substrate.
