Effect of Ni-P-Zn electroless bath parameters, such as concentration of reactants, pH level and deposition time, on corrosion characteristics of as-plated coatings were investigated. Energy Dispersive Analysis of X-ray (EDAX) was performed to calculate chemical composition of the deposited coatings. SEM imaging has been employed in order to study the surface morphology of the coated samples. Corrosion resistances of the obtained coatings were tested via potentiodynamic polarization experiment. According to the results, the optimal bath composes 10 g/l and 15 g/l of reducing agent and zinc agent, respectively. The pH value showed an amount of 10.5 and deposition time is 60 min. The solution results a coating layer which shows the best corrosion resistance with corrosion current density of 0.23 µA/cm².
