“…Based on the nucleation model [30,31], the oxide formation does not start homogeneously on the metal surface, but tiny solution seeds appear scattered at given points. The process takes place so quickly that a homogeneous, continuous oxide layer can form.…”

The A356 alloy is commonly used in the foundry industry to produce high-stressed automotive components, such as motor frames and cylinder heads. The aim of this work was to investigate how the mechanical and tribological properties of this alloy can be improved by applying an anodizing process. The properties of the oxide layer formed by anodizing using oxalic acid at low temperatures were characterized by different analytical and tribological methods. The combination of tribological methods with standard measurement techniques—such as hardness measurement, layer thickness measurement, as well as the analysis of the morphological characteristics—was used to track the layer evolution during wear developments.

“…[10][11][12][13][14][15] To that end, sulfuric anodization could be a suitable option as it brings satisfying results for corrosive protection when the oxide layer is properly sealed. 16,17 Indeed, the oxide layer grown during the anodization process is porous (even columnar on pure aluminum substrates) [18][19][20] and a sealing step is generally performed, for instance using hot water and forming boehmite 3,21 (aluminum oxide hydroxide AlOOH), to provide better protection. 16,17,22 Thus, lling the pores decreases the propagation of atmospheric pollutants and improves corrosion resistance of the material.…”
