Phase constitution, microstructure and properties of pulsed laser-clad ternary CrNiTi medium-entropy alloy coating on pure titanium

A ternary CrNiTi medium-entropy alloy (MEA) coating with excellent surface performance (hardness and wear resistance) was successfully prepared on pure Ti sheet by pulsed laser cladding. Microstructural characteristics of the MEA coating were probed by combined use of multiple characterization techn...
