In: INTERNATIONAL LATIN-AMERICAN CONFERENCE ON POWDER TECHNOLOGY, 4th, Nov. 19-21, 2003, Guaruja, SP. <b>Proceedings...</b> Disponível em: http://repositorio.ipen.br/handle/123456789/16439.http://repositorio.ipen.br/handle/123456789/16439In this study a corrosion protection method was used with AISI 304 SS filters and its effect on their corrosion resistance was evaluated in a sodium chloride solution (0.5 mol/L). The corrosion resistance of the surface treated filters was investigated at increasing temperatures, from 22 °C to 100 °C. It was found that the treatment improved the corrosion resistance of the filters at all temperatures tested. The film formed was maintained on the filters surface during the whole period of test (3 weeks). Surface analysis of untreated and treated filters, after corrosion tests, supported the indication of the beneficial effect of the corrosion protection treatment evaluated in this study.openAccessstainless steel-304lfilterssintered materialscorrosioncorrosion protectionsurface coatingtriazolesaromaticssulfuric acidthin filmscorrosion resistancesodium chloridesaqueous solutionsTexto completo de eventohttps://orcid.org/0000-0002-4987-3334
