AbstractThe present study describes the anodic growth of TiO2 nanotube thin layer on stainless steel 304 in ethylene glycol/water/ammonium fluoride electrolyte. In this regard, pure titanium was coated on stainless steel 304 substrates by a physical vapor deposition magnetron sputtering (PVDMS) technique. The adhesion strength of the coating to the substrate was investigated. TiO2 nanotubes were generated on the top of the Ti coated substrates by means of anodization technique at a 25 V potential and times of 20, 40, and 60 min in an ammonium fluoride electrolyte solution. The anodized Ti-coated samples were heat-treated at 280 °C, 430 °C and 620 °C in a N2 gas furnace to attain diverse phases. The mechanical properties of TiO2 nanotube arrays coated substrate were explored by a nanoindentation apparatus. The results illustrate that the Young׳s modulus and surface hardness of TiO2 nanotube-coated substrates are increased with increasing annealing temperatures (280 °C, 430 °C and 620 °C). The scratch test results show that heat treatment at 430 °C and 620 °C can improve the adhesion strength of Ti/TiO2 coated samples by up to 2860 and 3140 mN, respectively.
