Abstract
A coated article system includes a substrate and a surface coating on the substrate. The surface coating is formed by depositing individual particles of a composite metal powder with sufficient energy to cause the composite metal powder to bond with the substrate and form the surface coating. The composite metal powder includes a substantially homogeneous dispersion of molybdenum and molybdenum disulfide sub-particles that are fused together to form the individual particles of the composite metal powder.
