Fabrication of Ni-ZrO2 Nanocomposite Coating by Electroless Deposition Technique

Abstract

This work aims preparation of Ni-based nanocomposite coating by electroless deposition method onto stainless steel (316L) substrate, the present work will compare the effects of incorporation of ZrO2 nanoparticles at different percentages (1.25 wt %, 2.25 wt %, and 4.25 wt %) Ni-based electroless deposition coating of the bath nanocomposite on the phase structure, microhardness, and corrosion resistance is studied. Where the structure and chemical composition of nanocomposite coatings were studied by using (X-ray), (SEM) and (EDS). of Ni - ZrO2 nanocomposite coating exhibits much-increased microhardness and remarkably improved corrosion resistance.
