ADHESION AND COMPOSITE WEAR RESISTANT COATINGS AND METHOD

摘要

Adherence coatings and methods for forming same are provided. Generally, the adherence coatings are utilized in combination with exterior wear-resistant coatings of, for example, at least one non-metallic element and a transition metal. The composition of the adherence coating is selected on the basis of the substrate and exterior coating compositions and generally contain one or more metallic elements. The adherence coating can be applied by sputtering, desirably in a manner to produce a columnar microstructure.
