| Popis: | Electrochemical anodizing is one of the processes that due to its practicality, versatility, and excellent results has been used for decades for the oxidation of any metallic surface and the formation of nanostructures. In the present work was anodized commercially pure titanium using a solution based on hydrochloric acid, ethylene glycol, and deionized water. Varying the voltage from 21 to 24 volts was observed the formation of tube-shaped nanostructures in the anodized samples like a characteristic growth due to the use of HCl in the solution. Using Raman spectroscopy were identified the vibrational modes corresponding to the anatase phase. Using Vickers Microhardness and Nanoindentation it was demonstrated that the mechanical behavior was favored in the sample obtained with 24 Volts and growth time of 60 minutes. Finally, the TiO2 layers obtained improved the friction coefficient value of the titanium sheet, reducing its value from 0.8 to 0.4. |
