玻璃碳表面氧化行为

Oxidizing behavior of the surface of glassy carbon

利用SEM对经不同氧化所得到的玻璃碳表面和截面进行观察和分析 ,结果表明玻璃碳的氧化行为并不是从最外表面开始 ,而是从次表层进行 。

Examining and analyzing of the glassy carbon surface and section which suffered oxidation for different time, results show that the oxidizing behavior of glassy carbon begins from the sub-surface instead of the normal surface, which resulted by the different state of stress between the matrix and the surface.
