Water-based plating solution for preparing titanium nitride coating as well as preparation method and application thereof

The invention relates to a water-based plating solution, in particular to the water-based plating solution for preparing a titanium nitride coating as well as a preparation method and application thereof. The water-based plating solution for preparing the titanium nitride coating comprises potassium salt, sodium metasilicate, a wetting agent, a stabilizer, a brightener and the like. The water-based plating solution for preparing the titanium nitride coating is cheap and efficient, the raw materials are easy to obtain, the cost is low, the preparation condition requirement is low, and high-price equipment does not needed to be used; the application range is wide and any shape surface can be met; and meanwhile, the thickness of the prepared thin film is better, and the protection performanceof the thin film can be remarkably improved. 本发明涉及一种水性电镀液，具体涉及一种制备氮化钛镀膜的水性电镀液及其制备方法与应用。所述的制备氮化钛镀膜的水性电镀液包含钾盐、偏硅酸钠、润湿剂、稳定剂、光亮剂等。该制备氮化钛镀膜的水性电镀液廉价高效，原料易得成本低，制备条件要求低，无需使用价格高昂的设备；且应用范围广泛，可满足于任意形状表面。同时所制备薄膜的厚度更优，可显著提升其保护性能。
