Thick CrN/AlN superlattice coatings deposited by hot filament assisted HiPIMS for solid particle erosion and high temperature wear resistance

There are needs for the development of advanced ceramic coatings for industrial applications, e.g. die casting dies, forming tools, injection molds, valves in oil and gas field, etc. In many cases, under very severe working environment when high pressure and high velocity solid particle erosion and/or wear at high temperatures are involved, traditional hard coatings with thickness of several micrometers may not be satisfactory. High quality...
