Microstructural, Mechanical and Wear Behavior of HVOF and Cold-Sprayed High-Entropy Alloys (HEAs) Coatings

HEAs powders, unlike standard alloys which contain one or two base elements, are new that multiple elements in the same quantity. These materials have outstanding physical and mechanical properties for this reason, of great interest material science community their application advanced industrial sectors. In investigation, cold spray (CS) high-velocity oxy fuel (HVOF) processes were used to deposit Cantor alloy (FeCoCrNiMn) coatings. Starting feedstock powders thoroughly characterized terms size, shape, phase elastic modulus. For CS process, coating deposition efficiency porosity could be optimized by varying gas pressure, temperature stand-off distance. case HVOF distance influenced thickness Besides, on coatings, corrosion tests 3.5% NaCl solution, as well rubber wheel, ball disk jet erosion carried out evaluate wear behavior. Also, benchmark behavior results compared 316L C-Steel bulks. The tribological study shows coatings deposited via promising protect parts components a harsh environment.
