    • The present invention relates to a process of and apparatus for forming a magnetic structure on a substrate (44) and also a magnetic structure formed by such a process and apparatus. The magnetic structure comprises a matrix in which magnetic particles are embedded. Apparatus (30) for forming the magnetic structure on the substrate (44) comprises a source of matrix material (32) which is operable to deposit the matrix material onto the substrate to thereby form the matrix. The apparatus (30) for forming the magnetic structure further comprises a source of magnetic particles (34) which is operable to deposit the magnetic particles onto the matrix as the matrix forms to thereby embed the magnetic particles in the matrix. Each magnetic particle comprises a core covered at least in part with a layer of metal, at least one of the matrix material and the core is of ferromagnetic material and the core and the layer of metal are of different materials.

    • Physical vapor deposition techniques are used to coat fine particulates suspended in a fluidization gas. In one embodiment, an electron beam is directed toward a target comprising a coating material to generate a vapor of the material which is subjected to a flow of carrier gas. The resultant directional physical vapor deposition cloud is introduced into a fluidized bed chamber which contains fine powder particulates to be coated suspended in the fluidization gas. As the directional vapor cloud passes through the fluidized bed, the suspended particulates are coated with the coating material. The fluidized bed may comprise a recirculating or non-recirculating fluidized bed. The system may be used to produce substantially unagglomerated fine powders having many different types of coatings.
    • 使用物理气相沉积技术来涂覆悬浮在流化气体中的细小颗粒。 在一个实施例中,电子束被引向包括涂层材料的靶,以产生经受载气流动的材料的蒸气。 将所得到的定向物理气相沉积云引入到流化床室中,该室包含待悬浮在流化气体中的待涂覆的细粉末颗粒。 当定向蒸汽云通过流化床时,悬浮颗粒被涂覆材料涂覆。 流化床可包括循环或非再循环流化床。 该系统可用于生产具有许多不同类型涂层的基本上未凝聚的细粉末。
