(A) Open circuit potential with immersion time for uncoated, TMS, and TMS+NH3/O2 plasma-nanocoated L605 coupon substrates. (B) Cyclic polarization curves for uncoated, TMS, and TMS+NH3/O2 plasma-nanocoated L605 coupon substrates. (C) SEM images for surface morphology of uncoated and plasma-nanocoated L605 coupons after immersion test. TMS stands for TMS plasma-nanocoated L605, and TMS+NH3/O2 stands for TMS plasma-nanocoated L605 with NH3/O2 plasma post-treatment.
