Effect of electroplating temperature on microstructure, corrosion, and wear behavior of Ni-P-W-TiO2 coating

Nickel-phosphorus-titanium oxide coating is fabricated on the AISI 304L steel substrate using the electroplating method. Electroplating is performed at temperatures of 55°C, 60°C, and 65°C, and the effect of electroplating temperature on microstructure, corrosion behavior, and wear behavior is investigated. The coatings are characterized using scanning electron microscopy (SEM). In order to investigate corrosion resistance, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) tests are performed in a 3.5% NaCl aqueous solution. A pin-on-disk test is employed to investigate the wear resistance of uncoated and coated samples. Sample micro-hardness is also measured by the Vickers hardness test. The results of potentiodynamic polarization and EIS tests show that the coating created at the temperature of 60°C has the highest corrosion resistance (7058 Ω.cm 2 ) compared with the samples coated at temperatures of 55°C (2115 Ω.cm 2 ) and 65°C (2289 Ω.cm 2 ). Moreover, the results of the wear and micro-hardness test show that the composite coating formed at the temperature of 60°C has the highest wear resistance and micro-hardness (677 Vickers) compared with the samples coated at temperatures of 55°C (411 Vickers) and 65°C (536 Vickers).
