This study assesses the potential of an amorphous-type steel for use as a thermal barrier coating (TBC) on aluminum surfaces. A high-alloy steel powder was deposited on aluminum 6061 substrates by plasma spraying. Coating samples were examined, then thermally cycled to failure. The coatings showed good microstructural stability up to 500 °C, but their spalling resistance was inferior to that of arc-sprayed stainless steel, probably due to lower initial bond strength.
