Microstructure and corrosion behavior of ALD Al2O3 film on AZ31 magnesium alloy with different surface roughness
There remains growing interest in magnesium (Mg) and its alloys, as they are the lightest structural metallic materials and potential metallic biomaterials.In spite of the greatest historical Mg usage at present, the wider use of Mg alloys remains restricted by the poor corrosion resistance.A nano amorphous film, as the composition of Al2O3, had no
