Atmospheric corrosion of aluminium in the northern Taklamakan Desert environment / S. Sun in Materials and corrosion, Vol. 61 N° 10 (Octobre 2010) 

Public ISBD [article]  in Materials and corrosion > Vol. 61 N° 10 (Octobre 2010) . - pp. 852–859 Titre : Atmospheric corrosion of aluminium in the northern Taklamakan Desert environment Type de document : texte imprimé Auteurs : S. Sun, Auteur ; Q. Zheng, Auteur ; J. Wen, Auteur Année de publication : 2011 Article en page(s) : pp. 852–859 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Aluminium;  atmospheric  corrosion;  desert  environment;  weight  loss;  SEM Résumé : Atmospheric corrosion of aluminium in the northern Taklamakan Desert environment in China was investigated through the field exposure over a period of 2 years and the laboratory-accelerated test of dry-wet cycles. The results demonstrated that aluminium 1050 suffered serious atmospheric corrosion in the field exposure, which resulted from high soluble salt content and a high pH value of surface desert soil deposited on the samples. The soluble salt in surface desert soil could sufficiently decrease the relative humidity at which corrosion current density suddenly increased. Moreover, aluminium suffered more serious corrosion when there was more soluble salt content in surface desert soil. Among those salts, magnesium chloride caused the most serious corrosion attack.
