This article shows the creation of ceramic films of the SiO2-TiO2 Organic Polymer hybrid system from Tetraethyl-Orthosilicate (Si (OC2H5)4) and Titanium Tetrabutoxide (Ti(OBu)4) synthesized through the sol-gel method in several volumetric concentrations of precursors. This hybrid system was deposited on AISI 304 stainless steel substrates through the dip-coating technique. Feasibility for obtaining hybrid and homogeneous coatings on this type of substrate and evaluating the surface properties was studies. For such a purpose, the coating microhardness and adhesion were studies. Additionally, the film surface was characterized through the SEM (Scanning Electron Microscopy). The study concluded that characteristics of films change in function of the volumetric amount of precursors used for creating films.Este trabajo muestra la conformación de películas cerámicas del sistema híbrido SiO2-TiO2-Polímero Orgánico, a partir de tetraetil-ortosilicato (Si (OC2H5)4), y tetra-butoxido de titanio (Ti(OBu)4) y sintetizado por el método sol-gel en diferentes concentraciones volumétricas de los precursores. Este sistema híbrido se depositó sobre sustratos de acero inoxidable AISI 304 mediante la técnica de inmersión (dip-coating). Se estudió la viabilidad de obtener recubrimientos híbridos homogéneos sobre este tipo de sustrato y evaluar las propiedades superficiales. Para tal efecto, se estudió microdureza y adhesión del recubrimiento. Adicionalmente, se caracterizó la superficie de las películas por microscopía electrónica de barrido (MEB). Del estudio se concluye que las características de las películas cambian en función de la cantidad volumétrica de los precursores utilizados en la conformación de las mismas.
