Effect of Temperature on Corrosion Behavior of Laser-Remelted CrFeCoNi Coating
نویسندگان
چکیده
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 lower temperature. breakdown potential a decreasing trend increasing solution. This passive film formed low had stability. impedance spectroscopy possessed charge transfer temperatures. mechanisms were also revealed.

15 صفحه اولThe effect of TiO2 concentration on microstructure, corrosion behavior and wear behavior of Ni-P-W-TiO2 coating
Nickel-phosphorus coatings (Ni-P) are widely used in industry due to their high hardness, corrosion resistance and very good mechanical and chemical properties. Oxide particles such as TiO2 can be used to increase the wear resistance of these coatings. In this study, the Ni-P-W-TiO2 composite coating was deposited on the AISI 304L steel substrate using the electroplating method. Electroplating ...
