Assessment of Electrodeposited Zn-ZnO-Agrowaste-Silica Sand Composite as Anticorrosion Material for Mild Steel Substrate in a Marine Environment

Abstract

MS is extensively used in oil and gas industries, but its inherent susceptibility to corrosive attack in marine environments with high C of Cl -is a shortcoming to its applications in such inevitable medium. Coating has been a popular means of mitigating steel structures corrosion. This work assessed the effect of Zn-ZnO based AW-SS composite as AC material on a MS substrate in a marine environment. The Zn-ZnO base was separately subject to CD with SS, DLFA and LSLA particulates on MS substrates. PDP method was used to ascertain corrosion behaviors of the coated samples in a simulated SW environment. The samples and microstructural properties were studied by a microhardness tester and SEM, respectively. The results indicated that the samples increased when they were coated by SS and LSLA higher C, which had the highest and lowest , respectively. The coatings CP improved visibly with SS, which had the highest value (61.4%), followed by DLFA (53.8%) and LSLA (44.3%). AW incorporated into Zn-ZnO is a potential AC material.
