a Representative pictures of AH36 coupons showing the concentration-dependent anti-corrosion effect of rMrCP20 at immersion time intervals of 0, 1, 3, 7 and 24 h, and after cleaning the coupons with 1% HCl. b Respective buffer solutions after 24 h of coupon immersion. c Field emission scanning electron microscope (FESEM) images and overlay of energy dispersive X-ray spectroscopy (EDX) map of pitting corrosions before and after removal of corrosion products on surface of coupons, with a pitting of ca. 300 μm diameter outlined. d ImageJ analysis to determine percentage of corroded area of AH36 coupons. Error bars represent the standard error (SE) from triplicate tests. e Weight loss of AH36 over a 24 h incubation period and corresponding inhibition efficiency at increasing concentrations of rMrCP20. Error bars represent the SE from triplicate tests.
