The characterization of coated surface was done by XRD analysis that shows the incorporation of coating peaks within peaks of substrate (SS 316L), SEM/EDS also used to identify the structure and elemental composition of coating layer and the results indicated the formation of titanium carbide with neodymium particles which distributed on the titanium thin film and the EDS analysis showed the presence of Ti, Nd, O and high percent of C. AFM analysis indicated the increasing in surface roughness from 52.20 nm to 176.7 nm after coating with more valleys and peaks in two and three dimensions images, as well as more resistant for wear after coating from Abbott-Firestone results. The results of corrosion measurement showed the more positive corrosion potential for coated surface and decreasing in corrosion current density to obtain protection efficiency equal to 97.11% due to ability of the coating layer to isolate the substrate from corrosive environment.
