Description

The work is aimed at the development of an oxidation/corrosion resistant environmental barrier coating system on steel substrates. After stabilizing the coating slurries, double layers consisting of a bond coat applied by dip coating and a top coat with passive fillers deposited by spray coating were prepared on stainless steel substrates. After thermal treatment in air at 800 °C, uniform and crack-free composite coatings on stainless steel with a thickness up to 90 μm were prepared. The high temperature oxidation behavior of coated and uncoated samples in atmosphere of synthetic air was investigated at the temperatures up to 1000 °C. The tested layers provide effective protection from oxidation at 900 °C and 950 °C, while no significant corrosion damage was observed.
