Abstract

Use of Mg alloy structural parts can enable lightweight automobiles for improved energy efficiency. High corrosion susceptibility of Mg alloys, however, remains as a technical challenge against their application in vehicle-structures. This work investigates open-air plasma assisted Si–O–C coating as a corrosion barrier for AZ91D Mg alloy. The open-air plasma coating does not involve wet chemical process and is amenable to the industries experienced in other plasma-based processes. As-deposited coatings on AZ91D substrates were characterized by advanced microscopic characterization techniques, including SEM, STEM, and EDS. Corrosion evaluation was performed using electrochemical impedance spectroscopy, polarization, and H₂ collection measurements in 3.5 wt.% NaCl solution. Post-immersion AZ91D samples, that were uncoated or Si– O–C coated condition, were also characterized by SEM, STEM, and EDS. The results indicate that plasma assisted Si–O–C coating delayed the initiation of corrosion and the progression of corrosion attack.
