Abstract

BAUTISTA-RUIZ, Jorge. Anticorrosive and Biocompatibility Characterization of Silicon-Titanium-Zirconium Coatings Synthesized by Sol-gel and Deposited on Substrates 316L. Inf. tecnol. [online]. 2018, vol.29, n.1, pp.201-210. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642018000100201.

The ternary systems [Si/Ti/Zr: 10/70/20] and [Si/Ti/Zr: 10/20/70] were synthesized via sol-gel and applied on 316L stainless steel substrates by dip-coating. In the coatings obtained, the corrosion response was evaluated in a simulated physiological solution using potentio-dynamic polarization curves. The cellular biocompatibility of osteoblasts was studied; Substrate-coating adhesion, and the surface topography and the roughness in the coatings. The results of this study allow establishing a high degree of anticorrosive effectiveness and good biocompatibility. Sol-gel uncoated coatings establish their potential as an anticorrosive barrier as a function of the ternary system applied to the 316L stainless steel substrate.

Keywords : anticorrosive properties; sol-gel; silicon-titanium-zirconium; biocompatibility; adhesion.
