Protection of materials by advanced high temperature coatingsRoland Streiff

Coatings are mandatory to protect hot components in turboengines and energy producing systems. The materials or alloys of these components are, indeed, subjected to a number of attacks which include oxidation, sulphidation, carburisation, chlorination, fluorination, hot corrosion by molten salt deposits and erosion/corrosion. Since 40 years a considerable number of coatings have been perfected to answer this problem. In this paper the wealth of available coatings and coating deposition processes are reviewed and a classification is proposed to shed some light in this maze of coatings.
