Abstract
Methods for coating a substrate and methods of shaping a workpiece comprise formation and use, respectively, of a surface or substrate comprising a first phase selected from nitrides, carbides. carbonitrides, borides, sulphides, chalcogenides, oxides, and silicides, and a second phase selected from nitrides, carbides, carbonitrides, borides, sulphides, chalcogenides, oxides, and silicides, wherein said second phase comprises a multiplicity of discrete portions positioned into the first phase, with these multiplicity of portions comprising a continuous second phase, and made thereof, coating and articles, especially machining, cutting and shaping tools, wearparts, and methods of making and using the composition, coating and articles.
