Surface strengthening and self-lubrication enhancement of CoCrNi medium-entropy alloy by powder-pack boronizing

The CoCrNi medium-entropy alloy (MEA) exhibits an impressive ductility, but its low hardness (∼352 HV) and poor wear resistance limit its engineering applications. In this study, a significant increase of surface hardness and enhancement of self-lubrication were achieved for the CoCrNi MEA using pow...
