Study on Polarization Properties of High Entropy Functional Alloys of Spintronic Organic Magnetic Materials

To further improve the surface characteristics of 45 Mn steel, a composite coating of FeCoCrNiCu with high bulk entropy was applied by EDM deposition. The high entropy alloy electrode FeCoCrNiCu with a diameter of about 3 mm was cast by vacuum casting. Then the high entropy alloy deposition layer prepared on 45 Mn 2 steel matrix by EDM is introduced. A three-electrode system was used to study the corrosion of electrochemosensors in NaCl solution containing 3.5% by polarization curves and EIS tests. The experimental results show that the FeCoCrNiCu coating is continuous and smooth. And has an easy-to-use FCC design. The surface of the layer should be convex and uneven. Its appearance shows a typical “sputtering” pattern shape, and the mean cube root deviation Rq of surface roughness is controlled at about 4 μm. The high entropy metal alloy matrix at various WC levels comprises the simplest face-centered cubic structure (FCC) and body-centered cubic structure (BCC). With the increase of WC concentration, the FCC phase concentration of the matrix continued to decrease, while the BCC phase concentration continued to increase. However, WC particles are rapidly hydrolyzed and fully dissolved in FCC and BCC phases in the laser cladding reaction, which does not lead to more complex and changeable carbide phases. The high entropy alloy coating of FeCoCrNiCu can effectively improve the corrosion resistance of the substrate.
