摘要： A process for the corrosion protection of metals such as magnesium, aluminium or titanium, where at least two steps are used, including both plasma electrolytic oxidation and chemical passivation. The combination of these two processing steps enhances the corrosion resistance performance of the surface beyond the capability of either of the steps in isolation, providing a more robust protection system. This process may be used as a corrosion protective coating in its own right, or as a protection-enhancing pre-treatment for top-coats such as powder coat or e-coat. When used without an additional top-coat, the treated parts can still retain electrical continuity with and adjoining metal parts. Advantages include reduced cost and higher productivity than traditional plasma-electrolytic oxidation systems, improved corrosion protection, greater coating robustness and electrical continuity.

摘要翻译： 使用至少两个步骤的金属（例如镁，铝或钛）的腐蚀保护方法，包括等离子体电解氧化和化学钝化。 这两个处理步骤的组合增强了表面的耐腐蚀性能，超出了孤立的任一步骤的能力，提供了更强大的保护系统。 该方法本身可用作防腐蚀涂层，或用作顶部涂层（例如粉末涂层或电泳涂层）的保护增强预处理。 当没有额外的外套使用时，经处理的部件仍然可以保持与金属部件的连接和连接。 优点包括降低成本，提高生产率，比传统的等离子体 - 电解氧化系统，改进的腐蚀保护，更好的涂层鲁棒性和电连续性。
