Abstract

Eine Legierung aus Aluminium und Titan wird als hochtemperaturbeständiger, korrosionsfester Beschichtungswerkstoff für warmfesten Stahl zum Schutz vor Korrosion in Anlagen mit Prozessgasen verwendet, welche einen sehr niedrigen Sauerstoffpartialdruck ("reduzierende" Atmosphären) im Bereich von 1x10-50 Pa bis 1x10-22 Pa, insbesondere 1x10-29 Pa bis 1x10-25 Pa haben und den Beschichtungswerkstoff bis zu 700°C erwärmen und die auf Grund ihres Gehaltes an Kohlenstoffverbindungen eine hohe Kohlenstoffaktivität aufweisen. Der Beschichtungswerkstoff hat einen Aluminiumgehalt von 22 - 56 Atom%.An alloy of aluminum and titanium is used as a high temperature-resistant, corrosion-resistant coating material for heat-resistant steel to protect against corrosion in systems with process gases, which have a very low oxygen partial pressure ("reducing" atmospheres) in the range from 1x10 -50 Pa to 1x10 -22 Pa, in particular Have 1x10 -29 Pa to 1x10 -25 Pa and heat the coating material up to 700 ° C and which have a high carbon activity due to their content of carbon compounds. The coating material has an aluminum content of 22 - 56 atom%.
