MARCO AURELIO GONZALEZ ALBARRAN - Academia.edu (original) (raw)
Actually, I am working as a researcher professor in the materials science postgraduate department at the Universidad de Guadalajara. I have been working at the university for almost six years and my incorporation was trough the Cátedras CONACyT government project plan. During this six years and in collaboration with other research partners, I focused my research work in themes related to

The SiC + ZrB2 dispersed particles at the oxidation temperature of 1130 °C, dissolved at early stages, stabilizing the beta phase, diminishing the aluminum outward diffusion. The silicon at the BC/TC interface, or very close to it, behaved as a reactive element promoting the rapid formation and stabilization of α-Al2O3 (TGO), and a second scale layer of mixed oxides and silicon-rich compounds, jointly limiting inward oxygen diffusion and resulting in thinner TGO layers, whose kinetic oxidation follows a sub-parabolic behavior, increasing oxidation life-span.
