Effect of Varying Plasma Powers on High-Temperature Applications of Plasma-Sprayed AlCoCrFeNiTi Coatings.

In this work, the microstructure and mechanical properties of atmospheric plasma-sprayed coatings of AlCoCrFeNiTi prepared using gas-atomized powders at varying spray powers, are studied in as-sprayed and heat-treated conditions. Gas-atomized powders had spherical shapes and uniform element distributions, with major FCC phases and metastable BCC phases. The metastable BCC phase transformed to ordered and disordered BCC phases when sufficient energy was applied during the plasma-spraying process.
