Special Issue Information

Dear Colleagues,

Magnesium alloys, aluminum alloys, titanium alloys, and other related lightweight engineering materials are commonly used in the automotive, aerospace, and electronics industries, as well as in biomedical fields. Currently, it is also well known that their undesirable corrosion resistance in most service environments hinders their industrial applications. Therefore, understanding the different corrosion mechanisms of these lightweight engineering materials in different working environments and developing associated methods for their corrosion protection is imperative.

This Special Issue aims to provide an open platform for metallurgists, materials scientists, and engineers to share and disseminate recent research advances on the corrosion and protection of lightweight engineering materials. The potential topics of this Special Issue are diverse, encompassing alloying, processing, surface treatment, and electrochemical protection. It welcomes both experimental and theoretical studies and accepts original research and review articles.

While gas nitriding of steel is currently used in industry, nitriding of aluminum alloys remains an open challenge. The main obstacle is aluminum’s high susceptibility to passivation. The oxide film provides an effective barrier to nitrogen diffusion. Attempts to overcome this problem have mainly focused on glow discharge nitriding using cathode sputtering of an oxide layer. The produced AlN layers exhibit no diffusion zone and show limited performance properties. In this work, the effect of hybrid treatment aimed at producing diffusion layers of nitrides other than AlN on aluminum alloys was investigated on the model system of iron nitride–aluminum substrate. Hybrid treatment combines an electrochemical process involving the removal of the aluminum oxide layer from the substrate, its subsequent iron plating, and a further gas nitriding in high-purity ammonia. The obtained results prove that the hybrid treatment allows the production, at 530 °C/10 h, of diffusion layers of Fe3N iron nitrides on aluminum substrates with a nitrogen diffusion zone range in aluminum of ca. 12 µm. In alloys containing magnesium, its unfavorable effect on the nitrogen diffusion and the functional properties of the layers was observed. An interesting direction for further research is hybrid treatment of precipitation-hardened alloys without magnesium. Full article
