Corrosion Resistance of Nitric Acid Passivated Cr-Ni-Mo Stainless Steel

Article Preview

Abstract:

Austenitic stainless steels are considered materials with excellent corrosion resistance, and with acceptable mechanical properties. Therefore they are recommended for various constructional, industrial and biomedical applications. However they are prone to the pitting corrosion in aggressive chloride environments. The aim of this study is to evaluate the corrosion resistance of AISI 316Ti stainless steel with nitric acid passivated surface at the temperature range 22 – 80 °C in 1M acidic chloride solution. Evaluation of the corrosion resistance is based on the results of exposition immersion tests (visual and microscopic observation of attacked surfaces, mass losses of specimens) and the results of the electrochemical impedance spectroscopy (EIS) tests.
