Thin coatings, obtained by the sol-gel method, could find potential applications in medical, chemical and food industry. To achieve this, coatings need to have proper physicochemical, mechanical and protective properties. Titanium dioxide (TiO₂) and silicon dioxide (SiO₂) coatings have been applied onto the surface of a stainless steel (316L) by the solgel method using two techniques: dip-coating and painting. To determine the physicochemical composition of triple SiO₂ and TiO₂ coatings, samples were examined by Raman spectroscopy. Surface images obtained with the use of a scanning electron microscopy allow us to determine the surface morphology and continuity of the coatings. The surface morphology was examined before and after tensile tests. The static tensile tests and fatigue strength tests were conducted on a hydraulic testing machine MTS 810 with a measuring range of up to 100 kN. A preliminary research has confirmed that the coatings obtained by the sol-gel method have physicochemical, mechanical and protective properties that make it possible to use them as protective coatings.
