Process—structure—property relationship for plasma-sprayed iron-based amorphous/crystalline composite coatings

This study explores the fabrication of Fe-based amorphous/crystalline coating by air plasma spraying and its dependency on the coating parameters (plasma power, primary gas flow rate, powder feed rate, and stand-off distance). X-ray diffraction of the coatings deposited at optimized spray parameters showed the presence of amorphous/crystalline phase. Coatings deposited at a lower plasma power and highest gas flow rate exhibited better density,...
