PROPIEDADES MECÁNICAS DE PELÍCULAS HÍBRIDAS (ORGÁNICO-INORGÁNICO) SOBRE ACERO INOXIDABLE 304.

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 sot-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. [ABSTRACT FROM AUTHOR]
