    摘要： Extremely small, three-dimensional articles, such as fusion targets having glass shells (20 to 500 microns in diameter) are coated with alternate layers of colloidal materials. This is accomplished by depositing particles of opposite charge from colloidal suspensions (sols). Articles to be coated are suspended within a drop held in the open end of a closed capillary tube, and colloidal particles are deposited by dipping the capillary into the sols. Alternate monolayers of the particles adhere to the surface of the article. Multilayer coatings are built up by repeated alternate deposition of the monolayers from the sols. Between each deposition, the layers are rinsed with water and the water removed by dipping the capillary tube into a bath of water and then into a bath containing a water displacing agent such as ethanol or dimethyl sulfoxide.

    摘要翻译： 非常小的三维制品，例如具有玻璃壳（直径为20至500微米）的融合靶，涂覆有交替的胶体材料层。 这通过从胶体悬浮液（溶胶）中沉积相反电荷的颗粒来实现。 待涂覆的制品悬浮在保持在封闭的毛细管的开口端内的液滴中，并通过将毛细管浸入溶胶中沉积胶体颗粒。 颗粒的交替单层粘附到制品的表面。 通过从溶胶中重复交替沉积单层来建立多层涂层。 在每个沉积之间，用水冲洗各层，并通过将毛细管浸入水浴中然后进入含有置换剂如乙醇或二甲基亚砜的浴中而除去水。
