Fractographic Aspects of Stress Corrosion Failure of Zircaloy 2 in CH3OH HCL Solutions
نویسنده
چکیده مقاله:
Fracture surface of Zircaloy-2 specimens tested under constant crosshead speed in CH3OH/0.4 Vol. %HCI solution with and without selenium (25 ppm) addition was studied. Using a combined process of deformation and annealing, coarse grained material was also obtained and examined. Two modes of stress corrosion crack propagation were observed: an intergranular zone caused by stress assisted anodic dissolution, and a transgranular cleavage zone, due to hydrogen absorption.

AN INVESTIGATION ON CORROSION BEHAVIOUR OF A356-10 VOL.% SiC COMPOSITES IN HCl SOLUTIONS
In this study, corrosion behaviour of A356-10 vol.% SiC composites casted by gravity and squeeze casting is evaluated. For this purpose, prepared samples were immersed in HCl solution for 1h at open circuit potential. Tafel polarization and electrochemical impedance spectroscopy (EIS) were carried out to study the corrosion resistance of composites. The Tafel polarization and EIS studies of ...

Evaluation of corrosion inhibitors for steel in acidic media is important for some industrial facilities as well as is very interesting from theoretical aspects. Most of the effective inhibitors are organic compounds containing nitrogen, phosphorus and sulphur in their structures [1, 2]. Heteroatoms such as nitrogen, oxygen and sulphur are capable of forming coordinate covalent bond with metal ...
