Effect of Nickel Pulsed Electrodeposition Parameters on Deposit Microstructure and Corrotion Rate Aisi 410

Abstract

Nickel pulse electrodeposition is one of the coating methods that used to increase the corrosion resistance and improve the mechanical properties. In this study, nickel was used as the anode and martensitic stainless steel 410 was used as the cathode. The solution used in the method of nickel pulse electrodeposition include nickel sulfate, nickel chloride, and boric acid. Pulse electrodeposition parameters are variation of duty cycle of 70, 80, 90% and frequency variations valued at 0.1, 1, 10, and 20 kHz. Temperatures used in research nickel pulse electrodeposition at 50 ºC, with a current density of 15 A / dm² and 18 minutes. The Scanning Electron Microscopy analysis determine the microstructure and grain size changes after a nickel pulse electrodeposition. The polarization test determine optimum rate of corrosion when 90 % duty cycle and 20 kHz frequency.

The Effect of Nickel Electroplating on the Surface Hardness of Low Carbon Steel

“…The results are agreeing with the previous research [6] and [7]. Where it is known that the thickness of the coating increased as the plating time is longer [9].…”

“…Electroplating has been studied by many researchers for instance a study on the effect of temperature and time of electroplating copper-nickel plating on low carbon steel on thickness and hardness values [6]. From the results it was obtained that the thickness of the copper layer is 42.8 m at temperature of 40 o C with a time of 10 minutes, while for the nickel layer is 65.4 mm at temperature of 65 o C with a time of 20 minutes.…”
