Abstract
Coatings and methods for forming same are provided. Generally, the coatings are wear resistant disordered coatings of at least one nonmetallic element and a transition metal that are deposited on an article surface, such as a tool surface or other surface that is subjected to wear or friction. The resulting tools generally exhibit increased life with excellent lubricity thereby improving the surface finish of workpieces machined therewith. Adherence coatings are provided for achieving improved adherence of the wear resistant coating to the substrate.
