چکیده
FeCoCrNiMo high-entropy alloy (HEA) has attracted great interests due to its excellent corrosion resistance, but it suffers relatively low hardness and poor tribological performance. In this work, a systematic study on microstructural evolution behavior of equiatomic FeCoCrNiMoSix (x = 0.5, 1.0, 1.5) HEA coatings prepared by laser cladding (LC) Q235 steel substrates is reported. Confirmed X-ray diffraction analysis (XRD) energy dispersive spectrometry (EDS) results, these mainly consist Fe-rich FCC FeMoSi phases. The increase Si content leads greater lattice distortion promotes the formation Si-rich intermetallics, which can significantly improve wear resistance coatings. best achieved in FeCoCrNiMoSi1.0 coating, mechanism combined abrasive adhesive wear.

An AlCoCrCuFeNi high-entropy alloy (HEA) coating was fabricated on a pure magnesium substrate using a two-step method, involving plasma spray processing and laser re-melting. After laser re-melting, the microporosity present in the as-sprayed coating was eliminated, and a dense surface layer was obtained. The microstructure of the laser-remelted layer exhibits an epitaxial growth of columnar de...
