Analysis of Pitting Corrosion for 2219 Aluminium Alloy under Different Corrosion Circumstances

Abstract:

According to the observation of a metallurgical microscope, surface morphology of 2219 aluminium alloy under several corrosion circumstances, such as corrosion pits and grain boundary corrosion, is directly perceived. Furthermore, with a laser range finder, corrosion depth data can be measured, and by using some methods of data processing, the affection for this material of certain solution components and immersion time is studied quantitatively. This binary study mean not only provides both graphical and statistical analysis, but also gives the relationship between them, which makes the result more reliable.
