VEGA TRIANA, Juan Pablo et al. Tribological evaluation of sol - gel hybrid type coatings SiTiZr (10/20/70 y 10/70/20). Rev. ion [online]. 2012, vol.25, n.spe, pp.59-65. ISSN 0120-100X.

The sol-gel hybrid type coatings are used to create protective films at room temperature. Wear tests were developed on sol-gel hybrid coatings SiTiZr (10/20/70) and SiTiZr (10/70/20), to determine the coating tribological properties and the titanium and zirconium addition effect. Wear tests were developed on sol-gel hybrid coatings. Using a pin on disk type equipment coefficients of friction were determined. Scanning electron microscopy allowed e characterization of the wearing type. A profilometric study was conducted to determine the rate of wear. It was determined the thickness of the coating by analyzing the difference in height between the substrate and coating. It was concluded that the coating with a higher content of titanium has a lower coefficient of friction and wear.
