Due to the rebar corrosion problems, considerable resources are being allocated towards the repair and renovation of concrete structures. If these corrosion issues persist, essential structures face the risk of sudden collapse. To prevent such catastrophic failures, effective protective measures must be initiated during construction. This investigation aims to modify the surface of low-carbon steel rebar by electroplating with different coating thicknesses. The corrosion resistance efficiency was evaluated through various electrochemical corrosion tests. This study builds on the foundational work established by Brenner and Riddel regarding electroless nickel deposition. The primary objective was to ascertain the corrosion rate using gravimetric weight loss methods coupled with electrochemical testing. The performance of corrosion resistance was assessed at three distinct coating thicknesses of 10µ, 20µ, and 30µ, particularly under conditions with and without 3.5% NaCl. Potential time studies demonstrated the stability of the coating even in aggressive chloride environments during a one-month exposure period. Results from 12V accelerated impressed voltage tests revealed that the initial crack formation required twice as much time for the 20µ coated steel compared to others.
