Resumo: Anodizing of ferritic stainless steel has been used for decoration purposes to obtain a barrier effect. The most commonly used electrolyte for this process is INCO (5M H2SO4 + 2,5M CrO3). INCO electrolyte with glycerin addition induces the formation of ordered porous structures, because glycerin reduces the electrolyte conductivity. Ferritic stainless steel was anodized in electrolyte composed by 2M H2SO4 with glycerin addition in different concentrations, without chromium oxide addition. It was observed that the addition of 90 v/v% glycerin promoted a reduction in the electrolyte conductivity, which caused an increase in the anodizing potential. The glycerin addition to the electrolyte diminished the oxide dissolution in the electrolytic solution, promoting the formation of an oxide with an ordered porous structure.

El electrólito más comúnmente utilizado para este proceso es el INCO (5M H2SO4 + 2,5M CrO3). Con adición de glicerina induce la formación de estructuras porosas ordenadas, pues la glicerina reduce la conductividad del electrólito. Se anodizaron muestras de acero inoxidable ferrítico, en electrólito de 2M H2SO4 con la adición de glicerina en diferentes concentraciones, sin adición de óxido de cromo. Se observa que la adición de glicerina en un 90 v/v % promovió la reducción de la conductividad del electrólito, lo que ocasionó un aumento del potencial de anodización. Los resultados muestran que la adición de glicerina al electrólito redujo la disolución del óxido en la solución electrolítica y promovió la formación de un óxido con una estructura porosa ordenada.application/pdfengDyna : revista de la Facultad de Minas.
