Porcelanite stone powder and Cow bone were prepared and mixed with nano-Alumina. Nano Alumina was used with particle size20-30nm. Ni deposition was achieved on carbon steel specimens. The electrochemical corrosion performance of obtained coating was analyzed using potentio dynamic polarization test at four temperatures (30, 40, 50 and 60oC) The Ni/porcelanites-Al2O3-bone coating gets a new phase, which formed between Ni and other materials in XRD analysis. The coating has the highest efficiency compared with other coatings especially at 30 C0. ã2.50% NCl.
