The influence of plasma nitriding on the mechanical properties and microstructural deformation response of an Al0.3CoCrFeNi high-entropy alloy (HEA) were investigated. The results reveal that the presence of high density nano-nitrides on the surface tremendously enhances the hardness approaching to 14...
Recently, a?CoCrFeMnNi high-entropy alloy (HEA) was reported to possess excellent tensile strength and ductility at low temperatures. By plasma nitriding at 673?K, an expanded face-centered cubic structure was formed on the surface of this HEA. Another study found that, on ball milling, ...

The high-entropy alloy coating and the corresponding nitride coating have body-centered cubic (BCC) and face-centered cubic (FCC) structures respectively. Nitriding changes the phase structure and growth mode of the high-entropy coating, and the synthesized high-entropy nitride coatings are more ...
MicrostructureOxidationScanning electron microscopySEMThe nitrided layer on Al 1.3 CoCuFeNi 2 high-entropy alloys (HEAs) was prepared by plasma nitriding. The hardness, microstructure, tribological properties and adhesive strength of nitrided layer were studied. The microstructure and tribological property ...
reflected by the lowest mass loss and worn morphologies. The DT-316 received the slightest damage, and its excellent tribological performance was attributed to the following aspects: firstly, the nitriding layer had high surface hardness; secondly, the surface texture was able to capture wear debris...
