Pit nucleation on as-cast aluminiuim alloy AW-5083 in 0.01M NaCl

Abstract: The use of aluminium alloys in a wide range of technical applications is related mostly to the two facts: they facilitate weight saving of final products (if compared to the steel) and they are prone to spontaneous passivity due to the coherent surface oxide layer which impedes further reaction of aluminium with the environment. Among the commercial Al alloys, EN AW-5083 alloy is a representative non-heat treatable Al-Mg based alloy which possesses many interesting characteristics as a structural materia… Show more

“…The aluminium alloys of the 1xxx series are widely used in many commercial applications and therefore studies of these alloys are important in clarifying the effects of the constituents of high strength alloys on SCC behaviour (Trueba and Trasatti, 2009;Braun, 1995;Zhu and Van Ooij, 2003;Dolic et al, 2011;Dollah and Robinson, 2011).…”

“…The stress corrosion cracking (SCC) behaviour of aluminium alloys in aqueous environments such marine waters is of great importance for industrial applications. The aluminium alloys of the 1xxx series are widely used in many commercial applications and therefore studies of these alloys are important in clarifying the effects of the constituents of high strength alloys on SCC behaviour (Trueba and Trasatti, 2009; Braun, 1995; Zhu and Van Ooij, 2003; Dolic et al , 2011; Dollah and Robinson, 2011).…”

“…A morfologia, composição química e a distribuição das fases secundárias, formadas durante o processo de solidificação ou tratamentos termomecânicos, e dispostas na matriz de ligas de alumínio são conhecidas por induzir a corrosão localizada (Dorina et al, 2015;Birbilis et al, 2005;Proton et al, 2014;. Birbilis A presença de nanopartículas precipitadas e microimpurezas na superfície de ligas de alumínio tende a induzir a reação catódica, consequentemente, ocorre dissolução anódica de áreas adjacentes, pontos de nucleação de corrosão por pite (Dolić et al, 2011). Partículas intermetálicas, tais como Al 2 Cu Al 3 Fe favorecem a formação de células electroquímicas locais entre elas e a matriz rica em alumínio (Dolić et al, 2011).…”

Certos fatores podem ser associados com corrosão por pites em ligas de Al, a exemplo, o tipo e concentração íon agressivo, o pH do meio, a temperatura, ou ainda as características estruturais do filme de óxido passivo.…”
