ABSTRACT:
The invention provides coatings to achieve the best accommodation of chemical, physical, and mechanical properties desired in high performance and reliable glass molding and forming tools. The substrate material can be any ordinary die or tool material such as cast iron, stainless steel, platinum, tungsten carbide and silicon. A simple coating architecture consisting of a titanium adhesion layer and a Ni—Al—N or Ti—B—C—N working layer is provided. A NiAl working layer can meet the requirements of wear resistance in which abrasive and/or erosive wear is relatively low, while a Ti—B—C—N working layer is sufficient for processes operating at relatively low temperature or in vacuum or a protective environment. The coating architectures, from the coating/substrate interface to the outer most surface of the coating include an inner adhesion layer, an outer working layer and, optionally, one or more functionally graded material layers. The invention also provides methods of making these coatings.
