Scandium (Sc) is known to be one of the most effective alloying elements aluminum alloys. The only drawback its high price, but that could change quickly due promising results recent research on extraction. However, data how it affects anodic oxidation are very scarce. In this research, we analyzed a micro-addition Sc AlMg alloy growth mechanism and properties protective aluminium oxide layer d...

This work investigated the effect of friction stir welding (FSW) tool rotation rate and speed on grain structure evolution in nugget zone through thickness 10 mm thick AA5083/AA5754 weldments. Three joints were produced at different combinations FSW parameters. The texture using electron backscattering diffraction (EBSD). In addition, both hardness tensile properties investigated. It was found ...

In this study, the anodizing process based on use of tartaric sulfuric acid solution (TSA) was carried out metal substrate to evaluate for first time its effect adhesion strength and corrosion resistance aluminium alloy (i.e., AA5083) fibre basalt or glass) reinforced composite adhesive joints nautical applications. Furthermore, some TSA anodized samples were soaked in a NaOH investigate influe...

Fabrication of thick (more than 3 mm) hard coatings on Al-Mg alloys might provide better performance in terms increased durability, wear resistance and hardness compared with the unmodified material. In this study we fabricated Al-Co-Cr-Fe-Mn-Ni high-entropy alloy coating by wire-arc additive manufacturing onto AA5083 substrate. The aim is to investigate microstructure mechanical properties its...
