金属自钝化临界条件及控制

AUTOPASSIATON CRITICAL CONDITION AND CONTROL

利用相变理论及能量分析，对自钝化过程进行分析讨论，获得临界条件的物理意义、控制要素；加深对钝化现象及规律的认识，以便实践中更好地加以利用．

Using phase change theory and energy analysis, the process of the auto passiation is analysed and discussed in the paper.The physics meaning of the critical condition and control factor are gained.The phonomenon and rule of the autopssiation are known farther,it can be used in practice.
