The CrFeCoNi coating was fabricated by the laser remelting method. microstructure of detected. corrosion behavior at different temperatures investigated electrochemical measurements. Potentiodynamic polarization test results indicated that current density increased with increase in solution temperature 3.5 wt% NaCl and 0.5 mol/L H2SO4 solutions, suggesting exhibited higher resistance to attack ...
