Crude Alkaloid and Saponin Extracts of Agrimonia eupatoria Plant as Control Measure in Stainless Steel Corrosion in Hydrogen Tetraoxosulphate (VI) Acid Rich Area

Corrosion resistance of austenitic stainless steel in sulphuric acid

The resistance and susceptibility of austenitic stainless steel, Type 304, exposed to strong tetraoxosulphate (VI) acids (2 and 5 M concentrations) contaminated with sodium chloride at ambient temperatures was investigated by gravimetric and metallographic/scanning electron microscopy surface characterization methods. Scanning electron microscope (SEM) was used to examine and characterize the t...

Corrosion at Sulphide Inclusions in Stainless Steel

Auger analysis was performed using a high resolution scanning auger electron microscope and auger electron spectroscopy. Elemental auger contour maps for corroded sulphide inclusions in stainless steel were presented. It was found that the copper enriched-manganese sulphide inclusions were uniformly corroded, which might be due to CU2S deposition on the surface of corroding inclusions. In contr...

development of feminist poetics in adrienne rich

اشعار ریچ، به عنوان اشعاری که همیشه در حال تغییر و دگرگونی هستند، تجسمی از رشد و دگرگونیِ انسان هستد. پایان نامه ی حاضر، با تمرکز بر روی مراحل سیر شعری ریچ از تغییری در دنیا به عکس هایی فوری از یک عروس، سپس به شیرجه به درون کشتی شکسته و در نهایت به صبری عجیب مرا تا اینجا آورده، به بررسی این مراحل در قالب نظر شوالتر در رابطه با سه مرحله ی پیشرفت ادبی زنان یعنی مرحله ی زنانه، زن گرا و زن محور می پ...

Corrosion inhibitory action of some plant extracts on the corrosion of mild steel in acidic media

Corrosion Behavior of Stainless Steel Clad Rebar

Stainless steel clad rebar (SCR) was investigated because it may become a cost-effective means of controlling corrosion in concrete under very aggressive environments. Sound SCR (316L cladding) resisted corrosion in saturated Ca(OH)2 solution (SCS) with up to 5 wt% chloride. Cladding breaks on SCR induced significant corrosion of exposed underlying CS in SCS with only 1 wt% chloride. A computer...
