摘要： The present invention relates to a process for producing a coating on the surface of a substrate by plasma-electrolytic oxidation. Improved corrosion protection for lightweight metals, in particular for magnesium or magnesium alloys, is achieved by the process. Furthermore, biocompatible protective layers can also be produced on these materials, with the option of controlling degradation of the substrate. The layers are amorphous. They are produced by plasma-electrolytic oxidation in which the substrate is dipped as electrode together with a counterelectrode into an electrolyte liquid and a sufficient electric potential for generating spark discharges at the surface of the substrate is applied, wherein the electrolyte comprises clay particles dispersed therein. Substrates can therefore be any machine components, automobile components, railroad components, aircraft components, ships' components, etc., or bioimplants such as bone replacement materials or medical bone screws made of a lightweight metal such as magnesium or a magnesium alloy.
摘要翻译：本发明涉及通过等离子体电解氧化在基板的表面上制造涂层的方法。通过该过程可以实现轻金属，特别是镁或镁合金的改进的防腐蚀保护。此外，还可以在这些材料上产生生物相容的保护层，并且可以选择控制底物的降解。这些层是无定形的。它们是通过等离子体 - 电解氧化制备的，其中将基底作为电极与反电极一起浸入电解质液体中，并且施加足够的电位以在基底表面产生火花放电，其中电解质包括分散在其中的粘土颗粒。因此，底物可以是任何机械部件，汽车部件，铁路部件，飞机部件，船舶部件等，或诸如骨替代材料或由诸如镁或镁合金的轻质金属制成的医用骨螺钉的生物体。
