“镀铬”是许多日常用品普遍采用的电镀层。它不仅由铬镀层组成,而且在很薄的铬层下面还有一层或多层镍镀层。镍层的厚度(5～50微米)比铬层(0.1～0.5微米)厚得多。因此,整个镀层的光亮性和整平性应归因于镍层,而最后的色泽则是取决于铬层。铬层除了有引人注目的色泽外,还有其它好的特 Chrome is the plating commonly used on many everyday items. It consists not only of chrome plating, but also one or more layers of nickel under the very thin chromium layer. The thickness of the nickel layer (5 to 50 microns) is much thicker than that of the chromium layer (0.1 to 0.5 microns). Therefore, the brightness and flatness of the entire coating should be attributed to the nickel layer, and the final color is determined by the chromium layer. In addition to the chrome layer attractive color, there are other good special
