Stainless steels are widely used in engineering activities due to its chemical and mechanical features that offer high corrosion resistance as well as a good relationship of mechanical strength, resistance to high temperatures. Several methods known in surface engineering can be used to optimize the properties against corrosion of this kind material. The coating adhesion mechanism is a chemical anchor, which can provide the necessary protection for steel and used in various industrial and construction applications. This work displays the evaluation of performance against corrosion at high temperatures of a steel 316L with oxide coatings Ti-Zr-Si deposited by sol gel, which allows obtaining a ceramic system, deposited and analyzed with a mono, bi and tri-layer architecture presenting the results for each of them, carried out an analysis of loss of weight, chemical composition by energy dispersive X-ray (EDS) and scanning electron microscopy (SEM). The coating tri-layer 10/70/20 showed better corrosion protection at high temperatures, less cracking and roughness changes.
