摘要：

磷化是提高镁合金耐蚀性的重要工艺过程。磷化膜的制备以合金/溶液界面为场所，耦合了多个物理、化学

和电化学过程。首先，本文从磷化动力学入手，对近年来镁合金表面磷化膜制备的研究进行总结，并将磷化

过程分解为基体的电化学腐蚀、合金/溶液界面离子的反应与扩散、磷化膜的异相结晶 3 个串联的子过程。

其次，以时间为序分析合成参数对磷化调控的作用，以阐明各种因素对镁合金磷化的影响，并得出磷化过

程中温度、基体处理方式、pH 值等多种因素的自耦合以及与 3 个磷化子过程的多重交叉耦合是理解磷化

膜形成机制的难点。最后，对镁合金表面磷化膜制备的研究方向提出展望。

Abstract:

Phosphating is an important technological process for enhancing corrosion resistance of magnesium alloys. The

preparation of phosphating films takes the interface of the alloy/solution as place, coupling multiple physical,

chemical, and electrochemical processes. Firstly, this paper commences with the kinetics of phosphating to summarize the recent research of preparations of phosphating film on magnesium alloys surface and divides the phosphating process into three consecutive sub-processes: the electrochemical corrosion of the substrate, the reaction

and diffusion of ions at the alloy/solution interface, and the heterogeneous crystallization of the phosphating film.

Secondly, in chronological order, the role of synthesis parameters in phosphating regulation is analyzed to clarify

the influence of various factors on the phosphating of magnesium alloys. It is concluded that the self-coupling of

multiple factors such as temperature, substrate treatment methods, pH, etc., and the multiple cross-couplings with

the three phosphating sub-processes are the difficulties in understanding the formation mechanism of the phosphating film. Finally, the research direction on the preparation of phosphating films on the surface of magnesium

alloys are prospected.
