Firstly, the reaction thermodynamics was analyzed. Then, the reaction mechanism was studied, and the results are as following:① Ca moves to the surface of Dy〓O〓 by vapor phase;② Dy〓O〓 reduced to Dy by Ca is fast;③ Dy moves to the Fe surface mainly by vapor and various Dy-Fe alloys are produced gradually;④ The forming process of DyFe〓 may be described by Contracting Core Model;⑤ The rate-controlling step of the reaction is the Dy diffusing toward contracted and nonreaction nuclear center Fe.

首先考察反应的热力学可能性；其次探讨反应机理；通过实验确定：①Ca主要以气态形式迁移到Dy〓O〓表面参与反应；②Dy〓O〓被Ca还原为Dy的速度很快；③Dy主要以气态形式迁移到Fe表面逐级生成Dy-Fe合金；④DyFe〓的形成过程可以应用收缩核模型来描述；⑤Dy通过DyFe〓产物层向缩小的未反应核中心Fe的扩散是反应的控速步骤，通过动力学计算确定：还原扩散反应的表观活化能E〓=45kJ/mol。

The results show that dynamic leaching of heavy metals increases with decreasing pH values on the whole, but the relativity is not significant. The leaching concentration is negatively correlated with time. The calculation results show that the elements with the largest cumulative leaching amount are Fe, Mn, Zn and As, and those with the smallest amount are Pb, Sn, Hg and Cd. The elements with the highest stage lixiviating rate are Ni, Co, Cr, Mn, Cd and Cu, and that with the lowest rate is Fe. The elements with the highest values of cumulative lixiviating rate and cumulative lixiviating intensity are Cr, Mn, Co, Ni and Zn, and that with the lowest ones is Fe.

Process and mechanism of electrodeposited Zn-Fe-Si02 composite coatings were studied, including some contents as follow: Potential-pH plots of Zn-H2O and Fe-H2O systems were drawn, and the thermomechanical analysis was made. Results showed that the region of zinc and iron's codeposition was wide, which provided theoretic basis for electrodepositing Zn-Fe alloy. But the balance potential of zinc was greatly different from iron's, so in order to make zinc and iron codepositing, some complexant must be added into electroplating solution.

本文研究了电沉积Zn-Fe-SiO_2复合镀层的工艺和机理，主要包括以下几个方面：绘制了Zn-H-2O系和Pe-H_2O系的电位-pH图，并对其进行了热力学分析，结果表明，锌和铁发生共沉积的区域很大，这就对电沉积Zn-Fe合金的可能性提供了理论依据，但是锌和铁的平衡电位差别较大，所以，必须在镀液中添入一定量的配合剂才能使锌铁产生共沉积。

And comparison of their most stable surfaces with the body-centered cubic Fe shows that these carbide surfaces have lower surface energies than the most stable (110) surface of body-centered cubic Fe, indicating that the surface thermodynamics favor carburization at Fe surfaces.
