How does SEM contribute to the understanding of corrosion mechanisms in Mg alloys?5 answersScanning Electron Microscopy (SEM) plays a crucial role in elucidating corrosion mechanisms in Mg alloys by providing detailed microstructural information. SEM allows for the visualization of the surface morphology, grain structure, and corrosion products, aiding in the identification of corrosion sites and mechanisms. For instance, SEM analysis revealed the presence of nano-spaced basal plane solute-enriched stacking faults (SESFs) within fine grains in Mg alloys, which weakened the galvanic tendency and enhanced corrosion resistance. Additionally, SEM imaging highlighted the formation of protective surface films containing Al2O3, MgO, and Mg(OH)2 in Mg alloys, contributing to improved corrosion resistance initially but showing susceptibility to pore formation upon long-term exposure to chloride solutions. Overall, SEM provides valuable insights into the microstructural changes and corrosion behavior of Mg alloys, aiding in the development of corrosion-resistant materials.
