Estudo Comparativo Da Resistência À Corrosão De Aços Revestidos Pelos Processos De Galvanização a Fogo, Galvannealing E Galvalume 

Abstract: ResumoEste trabalho estuda comparativamente a corrosão de revestimentos à base de zinco sobre aços. Para tanto, é analisado o comportamento eletroquímico dos revestimentos sobre aço livre de intersticiais: zinco galvanizado a fogo (GI), galvanneal (GA) e galvalume (Zn55Al) em meio contendo cloreto por voltametria cíclica e pela Técnica de Varredura com Eletrodo Vibratório na seção transversal, com e sem a incidência simultânea de luz branca. Os revestimentos também foram caracterizados por Microscopia Eletrôni… Show more

“…The discolorations were observed mainly where the bamboo particles are visibly apparent and presented after aging with a burnt brown aspect. However, as recommended by [Santos et al 2013], when natural aging is caused by solar radiation, its effects are visible only on the surface layer of the sample. To confirm this observation, a laminate of 3 mm of depth was removed from the upper face of the specimen and is illustrated in Fig.…”
