Corrosion Resistance and Adhesion Properties of Electrophoretic Deposited Nano TiN Powder

The purpose of this study was to create TiN films on 430 stainless steel by electrophoretic deposition. The microstructure of the coatings was investigated by SEM. The results of the X-ray diffraction showed that after the sintering, apart from the titanium nitride, no secondary phase was observed. Sintering at 1200 °C for 1 h reduced porosity and increased adhesion between particles. Corrosion current density and corrosion potential were obtained for the best coated sample of 6.3 μA.cm-2 and-332 mV (vs. SCE) versus 37 μA.cm-2 (decreased to one sixth) and-453 mV (vs. SCE) for bare 430 steel, respectively. Rockwell indentation test according to VDI 3198 standard and the type and volume of the fracture area was used to evaluate the interfacial adhesion of the coatings. The results showed that all coatings resist shear stress and prevent a wide range of delamination, however the 1200 °C sintered sample has more adhesion strength.
