Thin AISI 430 ferritic stainless steel sheets containing 18% Cr were hardened by continuous-wave laser beams under different conditions. A symmetric double treatment platform was developed to operate two lasers simultaneously in order achieve a homogenous microstructure through the specimen and avoid overheating associated with single treatments on one surface. The influence of linear energy de...

The enormous demands for metal implant have given rise to a search for cheap material with good bio-tolerability and resistance to corrosion. Although stainless steel has these properties and is widely used for this purpose, its long term application is still a concern. The corrosion resistance of stainless steel depends on the passive layer. Herein, chemical surface treatment, including passiv...

in this paper, the electrochemical behaviour of passive films formed on aisi 321 stainless steel (aisi 321)immersed in 0.1 m naoh + 0.1 m koh solution was evaluated by different electrochemical techniques. forthis purpose, passive films were formed at open circuit potential for 1 to 12 hours and then electrochemicalmeasurements were done. the polarization curves suggested that aisi 321 showed e...

In this study, electrochemical behaviour of passive films formed on AISI 316L stainless steel (AISI 316L) in three acidic solutions concentrations (0.3, 0.6, and 0.9M HNO3) under open circuit potential conditions were evaluated by potentiodynamic polarization, Mott–Schottky analysis and electrochemical impedance spectroscopy (EIS) techniques. The potentiodynamic polarization results showed that...

The present study focused on stress corrosion cracking (SCC) and corrosion behavior of ferritic stainless steel (grade 430) in activated methyl diethanolamine (aMDEA) solution, which is classified as a tertiary amine. In this regard, cyclic polarization and U-bend tests were performed in CO2 loaded aMDEA with different concentrations at 25 and 70 °C to observe corrosion behavior and ...
