Oxidation behavior of Ni-TiO2 and effect of SDS on the coating

Surface modification is very important in the component in industry due to fracture. Fatigue, torsion and bending will be initiated from a surface. Electroplating is one of the way which can modify the surface. In this study Ni-TiO2 coatings were prepared on an AISI 430 stainless steel substrate by electrocodeposition in Watt’s plating bath containing TiO2 particles. Resistance to oxidation of Ni-TiO2 was studied after 200h in 800 0C. Results show better oxidation behavior were achieved after 200h in 800 ◦C while the cyclic oxidation worsen in the presence of SDS. Composite coatings were investigated by scanning electron microscope (SEM) and X-ray systems.
