摘　　要：将具有阻挡层的试样封装在具有不同CO2压力的石英管中加热，然后对阻挡层表面进行观察和XPS分析，并用相对灵敏度因子法对X射线光电子能谱分析结果进行了计算分析。结果表明：700℃加热后，在0．03MPaCO2条件下的阻挡层被破破坏；300—500Pa的CO2条件下的阻挡层完好，其中的C-H键和-OH键的量随保温时间的增长和CO2压力的增高而增高；阻挡层能够在300—500Pa的CO2、700℃的封闭小空间中连续工作300小时。A specimen with the barrier was put into a glass tube with different pressure of CO2 and heated to 700℃ for 300 hours,and then analyzed using x-ray photoelectron spectroscopy.The analyzed results obtained from x-ray photoelectron spectroscopy were calculated using relative sensitivity factor method.The results showed that the barrier was destroyed under the condition of 0.03MPa CO2.The barrier kept complete under the condition of 500Pa CO2 for 300 hours,and the quantity of O-H bond and C-H bond increased.It was concluded that the barrier could continue working for 300 hours under the condition of 500Pa CO2 and 700℃.
