• This research compared the corrosion behavior of the Ni plated and the un-plated Hastelloy C-276 and stainless steel 316 EAS coatings in 2M NaOH solution at 25°C using electrochemical technique. The results can be summarized that Ni plating of approximately 10 microns thick as a sealant can improve the corrosion resistance of the EAS coatings. The as sprayed Hastelloy C-276 coating exhibits higher corrosion rate than the as sprayed stainless steel 316 coating. The corrosion behavior can be improved further by smoothening of the EAS coating surface before plating. The corrosion resistance of the smoothened Hastelloy C-276 coatings, both plated and un-plated, are superior to those of the stainless steel 316 coatings.
