Thermisch gespritzte Korrosionsschutzschichten für sulfidierende Atmosphären (Thermal Sprayed Coatings for Reducing Sulfidizing Atmospheres at High Temperatures)

Intermetallic TiAl coatings were applied to ferritic steels using plasma and HVOF spraying methods. The specimens were then placed in reducing sulfidizing atmospheres for high-temperature corrosion testing. This paper describes the experiments that were performed and presents and analyzes the results. In general, for the reasons given, the coatings performed better in an Ar-H₂-H₂S-atmosphere than in one containing CH₄. Paper text in German.
