ملخص المقالة :
A nanocomposite coating including titanium oxide nanotube and CuO is synthesized on the commercially pure titanium using electrochemical anodizing at 30V for 2 hours in an electrolyte containing Ethylene glycol, water and ammonium fluoride in combination with a magnetron spattering process to produce a thin layer of copper. A thin layer of copper deposited on the titanium prior to anodizing as well as after the anodizing process and then the samples were thermally oxidized under pure oxygen atmosphere at 300°C for 1 hour. Microstructural evaluations revealed that titanium nanotubes were formed over the metallic surface. In the case of the pre-coated sample, CuO particles were detected over and in the nanotubes and for the post-coated sample, a contiguous layer of copper oxide was formed over the nanotubes. Wettability of the produced samples improved in comparison with the sample without copper. Also, the antibacterial activity of the copper-containing samples was better than the raw materials and the sample without copper
