Effect of centrifugal speed on the anticorrosive properties of bismuth-silicon coatings by sol-gel on 316L substrates

Abstract:

In this investigation, the compound Bi24Si40O2 was synthesized via sol-gel and applied on substrates of 316L stainless steel by spin coating varying speed. In the coatings obtained, the corrosion response in simulated physiological solution was evaluated by electrochemical impedance spectroscopy and polarization potentiodynamic curves. The morphology and surface topography was studied, also, were determined the microstructure, thickness values and roughness of the coatings. The results of this study allow establishing a high degree of anticorrosive effectiveness offered by the coatings as a function of the number of layers applied to the substrate and their possible application in the biomedical industry.
