The pitting propagation rate was evaluated by simulating occluded corrosion cell (SOCC), and corrosive characteristic of pits was studied by scanning electromicroscopy (SEM) and EPMA.
Here Raman microscopy and electro probe technique were used to identify the corrosion products and their locations on and within of ancient Yuan Dynasty bronze mirror from Lufeng of Yunnan province.
Results:Through electron microscopy, electro-acupuncture group has normal Schwann cells, rich organelles, especially the clear vision of rough endoplasmic reticulum integrity.
