5 结论
(1)可伐合金的可控氧化通过氧化温度和气氛来实现。在500℃N2-2.31%H2O-0.95%H2混合气氛下，1000℃N2-2.31%H2O-0.5%H2混合气氛下和1000℃N2-2.31%H2O混合气氛下分别氧化时会生成单一Fe3O4、单一FeO和Fe3O4与FeO的混合物。
(2)可伐合金在500℃N2-2.31%H2O-0.95%H2混合气氛下或1000℃ N2-2.31%H2O-0.5%H2混合气氛下氧化时，氧化动力学遵循线性规律，意味着氧气从混合气体向氧化膜的转移是决定性的一步。而在1000℃N2-2.31%H2O混合气氛下氧化时的氧化动力学遵循抛物线规律，铁离子的扩散是决定性的一步。
(3) 在1000℃N2-2.31%H2O混合气氛下，可伐合金发生内部氧化；但在另外两种工艺下氧分压较低，因此不会发生内部氧化。
