We should all know that there is an oxide film on the surface of the alloy aluminum coil, which can protect the alloy aluminum coil, but sometimes we will find that the oxide film will appear uneven color. So what's going on?
Electron microscopy and energy dispersion analysis are used to reveal structural features of an oxide film in the region of white deposit areas that are visually detected on the surface of cylindrical ingots of 6000 series aluminum alloy after

The crack defects in aluminum alloy castings were studied from the viewpoint of oxide bifilm, its morphology, composition, forming process as well as the effects of them on the mechanical properties of the casting were systematically investigated here.
