Structure and properties of composite aluminum oxide layers produced on magnesium alloys using hybrid method
Abstract
Unlike aluminium oxide surface layers, magnesium oxide layers obtained by anodising processes exhibit somedrawbacks, especially chemical instability in the presence of humidity, resulting in susceptibility to cracking andspalling. This work was dedicated to the development of a new hybrid method allowing us to produce compositealuminium oxide surface layers on magnesium alloys to ensure better performance properties than thoseachieved by magnesium oxide layers produced by commercial anodising. Composite aluminium oxide layerswere produced on magnesium AZ91D alloy using a three stage hybrid method: magnetron sputtering depositionof an aluminium coating, followed by anodising in classical or plasma electrolytic oxidation (PEO) variant,combined with final tightening of the layer by hydrothermal treatment. The structure and the properties of thecomposite oxide layers were characterised. The investigations proved that the hybrid method using classicalanodising is a promising method to improve the corrosion resistance of the AZ91D alloy much more efficientlythan commercial anodising, but at the cost of decreased wear resistance. Based on preliminary investigation, amodified variant of the hybrid method using PEO treatment was found to result in both high wear and corrosionresistant composite aluminium oxide layers on AZ91D alloy, making it a prospective solution.
