Studies from Ocean University of China Add New Findings in the Area of Surface and Interface Analysis (Surface characterization of growth process for cerium conversion coating on magnesium alloy and its anticorrosion mechanism)

By a News Reporter-Staff News Editor at Science Letter -- Research findings on Surface and Interface Analysis are discussed in a new report. According to news reporting originating in Qingdao, People's Republic of China, by NewsRx journalists, research stated, "Cerium conversion coating is successfully deposited on magnesium alloy AZ31 for corrosion protection. Deposition time on the influence of cerium conversion coating morphology, composition, and electrochemical properties has been investigated in detail."

The news reporters obtained a quote from the research from the Ocean University of China, "Morphological observation reveals that the cerium conversion coating is a porous agglomerate nanostructure. XPS indicates that the coating exhibits a time-dependent ingredient. Moreover, the coating is considered as a combination of magnesium oxide/hydroxide and cerium (III) and (IV) oxides/hydroxides. The results of electrochemical impedance spectroscopy indicate that the anticorrosion coating exhibits the best properties during deposition of 5 min."

According to the news reporters, the research concluded: "In view of the analysis, the anticorrosion mechanism is pioneered proposed because of the formation of H-bonding layer, which forms a reasonable barrier to Cl- ions."
