Abstract
The main activities of our research group are basic research, development and applications in various fields of plasma surface engineering. The purpose of this research work is to develop new PVD coatings with improved tribological properties. This includes process development and basic characterization of the coatings manufactured. The projects have been directed towards: - fundamental studies of physical properties of various binary, multicomponent and multilayer coatings - plasma diagnostics by Langmuir probe and by energy-resolved mass spectroscopy of ions during triode ion plating of transition metal nitrides and carbides - improvement of moulds for die casting aluminium alloys, hot extrusion of aluminium and hot forging manufacturing with PVD hard protective coatings and duplex treatment - development of PVD technologies as an environmentally clean alternative to electroplating and electroless processes - a study of interface interactions in bi- and multilayer structures during thermal annealing - preparation of standards in the form of multilayer structures for depth profile analysis - development of thin electrolyte films of stabilized zirconias (YSZ) for solid-oxide fuel cell (SOFC). In the metalworking and plastic working industry many different operations like cutting, forming, deep drawing, punching, plastic injection moulding, die casting, hot forging, cold and hot extrusion, etc. are used. For each of these operations some predominant tool failure mechanisms can be defined. The parameters which influence on wear and corrosion resitance of coatings are hardness, toughness, structure and chemical affinity. For each of these operations we try to find the best protection using appropriate PVD coatings. Recently we introduced the first research in Slovenia on replacement of electroplating coatings with plasma (PVD) metallic and ceramics coatings. Namelly electroplating is a major source of environmental pollution today. The environmental ordinances in well-developed countries have become so strict in the last years, that the production of galvanic coatings is restricted. Therefore new ecologically clean procedures, which should replace conventional techniques, have been developed in recent years. Among them PVD processes have good perspective because they avoid all of the environmental problems of wet chemical methods.
