| Abstract Scope |
Due to their high melting temperatures and excellent high-temperature strength, refractory metals inherit attractive properties as structural materials for industrial high-temperature applications. In particular molybdenum is a state of the art structural material in glass production, components for high temperature furnaces and special tools. It is also well known that molybdenum suffers from poor high-temperature oxidation resistance which restricts the use of pure molybdenum and its alloys such as TZM or MHC to low temperatures or requires essentially oxygen free atmospheres. However, this shortcoming can be overcome by the proper use of protective coatings. In this paper examples of successful industrial application of molybdenum protected by highly efficient oxidation barrier coatings will be presented. Aspects regarding processing, coating –substrate interactions as well as wear and corrosion mechanisms during the life cycle of a component will be discussed. Analytical aspects leading to a better understanding of the coating–substrate behavior will also be highlighted |
