Nano oxides reinforced high-entropy alloy coatings synthesized by atmospheric plasma spraying

Nano oxides reinforced high-entropy alloy coatings synthesized by atmospheric plasma spraying

The high-entropy alloy coatings reinforced with nano oxides were synthesized by the atmospheric plasma spraying (APS). The crystal structure, microstructure, surface morphology, hardness and wear resistance properties of the CoCrFeNiAl and CoCrFeNiMo high-entropy alloy coatings are investigated. For...
