Corrosion evaluation of superalloys Haynes 282 and Inconel 718 in Hydrochloric acid

Corrosion susceptibility of Haynes 282 (HY282) and Inconel 718 (IN718) superalloys in hydrochloric acid (HCl) at ambient temperature was investigated using gravimetric and electrochemical techniques. In the gravimetric study, corrosion rate of the superalloys in 0.5 M, 0.75 M, and 1 M HCl for 72 days was evaluated using weight loss method. The concentration of metallic ions in the 1 M electrolyte after the immersion test was estimated using...
