Corrosion of aluminium, stainless steels and AISI 680 nickel alloy in nitrogen-based fuels / I. Kap in Materials and corrosion, Vol. 63 N° 7 (Juillet 2012) 

Public ISBD [article]  in Materials and corrosion > Vol. 63 N° 7 (Juillet 2012) . - pp. 571–579 Titre : Corrosion of aluminium, stainless steels and AISI 680 nickel alloy in nitrogen-based fuels Type de document : texte imprimé Auteurs : I. Kap, Auteur ; M. Starostin, Auteur ; G. E. Shter, Auteur Année de publication : 2012 Article en page(s) : pp. 571–579 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Ammonium  nitrate  urea  fuels;  carbon  steel  and  aluminium;  corrosion  resistance;  nickel  alloy;  non-carbon  fuels;  stainless  steels Résumé : Nitrogen-based compounds can potentially be used as alternative non-carbon or low-carbon fuels. Nevertheless, the corrosion of construction materials at high temperatures and pressures in the presence of such fuel has not been reported yet. This work is focused on the corrosion of AISI Al 6061, 1005 carbon steel (CS), 304, 316L, 310 austenitic stainless steels (SS) and 680 nickel alloy in highly concentrated water solution of ammonium nitrate and urea (ANU). The corrosion at 50 °C and ambient pressure and at 350 °C and 20 bar was investigated to simulate storage and working conditions. Sodium chloride was added to the fuel (0–5 wt%) to simulate industrial fertilizers and accelerated corrosion environment. Heavy corrosion of CS was observed in ANU solution at 50 °C, while Al 6061, 304 and 316L SS showed high resistance both to uniform and pitting corrosion in ANU containing 1% of sodium chloride. Addition of 5% sodium chloride caused pitting of Al 6061 but had no influence on the corrosion of SS. Tests in ANU at 350 °C and 20 bar showed pitting on SS 304 and 316L and 680 nickel alloy. The highest corrosion resistance was found for SS 310 due to formation of stable oxide film on its surface.
