    • An apparatus and method for coating or treating powdered material, particularly ultrafine powders in the nanometer or submicron range of mean diameters, by electrolytic processes. A platen (30) is mounted for rotation upon a fixed shaft (20), and a rotary flow-through electrolytic cell (36) is mounted upon a platen (30) for rotation thereon, the cell's axis of rotation (B) being offset from the platen's axis of rotation (A). The cells axis of rotation (B) revolves around the platen's axis (A) as the platen (30) rotates. The electrolytic cell (36) accordingly undergoes a planetary rotation, as the cell (36) revolves around the platen's axis of rotation (A). The planetary rotation of the cell (B) allows the powdered material to be collected by centrifugal force and constantly agitated to promote uniform electroplating. An electrode array (44) and rolling contact system are supplied which allow electric potential to be applied only to those electrodes actually in contact with the powdered material to be treated.
    • 一种用于通过电解方法涂覆或处理粉末材料,特别是纳米或亚微米范围内的超微粉末的装置和方法。 安装用于在固定轴(20)上旋转的压盘(30),并且旋转流通电解槽(36)安装在压板(30)上以旋转,电池的旋转轴线(B)被偏移 从压盘的旋转轴(A)。 当压板(30)旋转时,单元旋转轴线(B)围绕压板的轴线(A)旋转。 当电池(36)围绕压板的旋转轴线(A)旋转时,电解槽(36)相应地经历行星旋转。 电池(B)的行星旋转允许通过离心力收集粉末材料并且不断地搅动以促进均匀的电镀。 提供电极阵列(44)和滚动接触系统,其允许电势仅施加到实际上与被处理粉末材料接触的那些电极。
