The invention provides the production of substantially Cr(Vl)-free black-chroming layers, preferably on automotive inside surfaces. The essence is the combination of a cathodic activation prior to the black-chroming operation with an ultrasound-augmented cleaning operation thereafter.FRANZ, WOLF-DIE...
首先，对钢铁零件进行电镀处理，以在其表面形成一层厚度为12微米的锌层。此锌层起到基础保护作用，为后续的处理提供稳定的基底。接着，进行镀铬处理。此步骤中，无需设定铬镀层的具体厚度，灵活性较高。镀铬层在表面形成后，具备改善颜色及提高涂漆附着能力的效果，同时，铬镀层可被染色，便于识别经过处理...

The free and immobilised biosorbent removed Cr(VI) efficiently with a maximum metal removal capacity of 55 and 40 mg/g, respectively. The biosorption mechanism was also investigated using Fourier transfer infrared and scanning electron microscopy. Immobilised spores of A. niger were more stable in ...
