The paper considers a new concept of alloy with high entropy (HEA) for biomedical applications. HEAs are different from the conventional metallic materials by more than five alloying elements, in proportions between 5% and 35% at., which may form simple solid solutions BCC and/or FCC phases instead complicated intermetallic ones. These specific features provide HEA excellent mechanical properties (hardness, strength, malleability), oxidation corrosion resistance, potential applications...
Potentiostatic electrodeposition was used to obtain CoCrFeMnNi high-entropy alloy (HEA) thin films on copper substrate. An electrolyte based a DMSO (dimethyl sulfoxide)-CH3CN (acetonitrile) organic compound for the HEA deposition. The microstructure of deposits before and after corrosion in artificial seawater investigated by scanning electron microscopy (SEM) energy dispersive spectrometry (EDS) investigation. SEM analysis revealed that compact uniform film consists 50 nm–5 μm particles...
