Special Issue Information

Dear Colleagues,

We cordially invite you to contribute your latest work for a forthcoming Special Issue entitled "Multifunctional Corrosion Resistance Coatings for Additive Manufacturing (AM) Alloys". Additive manufacturing (AM) is a fast-evolving metal processing approach used in a variety of fields for developing complex structures with customised properties. However, corrosion mitigation remains a key concern due to AM alloys' peculiar microstructure. This Special Issue focuses on research that provides insights into the development and characterisation of coatings for AM alloys. It covers the most recent developments in the manufacture of AM alloys, coating systems (inorganic/organic coatings, surface modification, composite coatings) on AM alloys, electrochemical characterisation of alloys/composite systems, and multifunctional aspects of coatings for active corrosion protection, as well as understanding coating–substrate interactions and surface functionalization to support active species inside protective coatings for a variety of applications.

Multifunctional corrosion-protective coatings are gaining widespread acceptance due to their versatility and ability to fulfil a wide range of specific demands. These coatings may provide adaptability, economic benefits, enhanced durability, thermal, electrical, and electrochemical responses, as well as suitable tribological properties (plasma electrolytic oxidation, anodic oxidation, PVD, CVD, etc.). These features make them the focus of research into multifunctional coating materials for active corrosion protection, with potential further applications in catalysis, environmental sciences, biocompatibility, superhydrophobic materials, self-healing, and other areas.

The scope of the issue includes fundamental and applied research topics such as the functionalization of protective coatings on AM alloys for active protection focusing on the control of the particular composition and morphological and structural features to tailor their physical, electrochemical, and other properties, which may allow new and/or improved responses to a set of requirements for multifunctional coating systems (e.g., catalysis, antibacterial response, self-lubrication).

Mg2Ni hydrogen storage alloy has the advantages of large hydrogen storage per unit mass, low price, and abundant resources, but there are shortcomings such as activation difficulties and poor kinetic performance. This paper improves the performance of Mg2Ni hydrogen storage alloy by adding Ti and Mn alloying elements. Mg1.6Ni1-xTi0.4Mnx (x = 0~0.3) hydrogen storage alloys with different Mn contents were prepared by the solid phase diffusion method. The physical structure and microscopic morphology of the prepared alloys were characterized using XRD and SEM techniques, and their charge/discharge and electrochemical properties were tested using a battery tester and an electrochemical workstation. The results show that the solid phase diffusion reaction of the prepared alloys resulted in the formation of the Mg phase with a layered structure, a Mg2Ni hydrogen storage phase, and intermetallic compounds Ni3Ti and Mg3MnNi2 phases. The presence of Ni3Ti and Mg3MnNi2 phases improved the activation properties and discharge capacity of the alloys. The alloys with Mn addition all reached the maximum discharge capacity at the first cycle. The maximum discharge capacity increased from 50.45 mAh/g without Mn addition to 96.67 mAh/g at x = 0.3. The maximum discharge capacity of the alloy increased to 165.52 mAh/g at 323 K. The maximum discharge capacity of the alloy increased from 50.45 mAh/g without Mn addition to 96.67 mAh/g. And its corrosion current density was reduced from 0.96 mA/g without Mn addition to 0.3 mA/g. Full article
