    • An aluminum-alloy article such as a fastener or rivet (40) is prepared by providing an aluminum-alloy article precursor that is not in its final heat-treated state, and in one form is in its solution treated/annealed state. A curable organic coating material is also provided. The method includes anodizing the article precursor, preferably in chromic acid solution and without chemical sealing during anodizing, applying the organic coating material to the aluminum-alloy article precursor, and precipitation heat-treating the coated aluminum article precursor to its final heat-treated state, thereby simultaneously curing the organic coating. If the aluminum alloy temper is of the naturally aging type, it is optionally lightly deformed prior to precipitation treatment aging. The approach may also be applied to articles that are not solution treated/annealed and aged, by first overly deforming the article precursor so that the curing treatment of the coating also partially anneals the article precursor to the final desired deformation state.
    • 通过提供不属于其最终热处理状态的铝合金制品前体,并且以一种形式处于其溶液处理/退火状态,制备诸如紧固件或铆钉(40)的铝合金制品。 还提供了可固化的有机涂层材料。 该方法包括阳极氧化制品前体,优选在铬酸溶液中,并且在阳极氧化期间没有化学密封,将有机涂料施加到铝合金制品前体,并将涂覆的铝制品前体沉淀热处理至其最终热处理状态 从而同时固化有机涂层。 如果铝合金回火是天然老化型,则在沉淀处理老化之前任选轻度变形。 该方法也可以应用于不经过溶液处理/退火和老化的制品,首先使制品前体过度变形,使得涂层的固化处理也部分地将制品前体退火到最终期望的变形状态。

    • A satellite dispenser (300) adapted to be coupled to a launch vehicle. The dispenser (300) includes a single-piece, integrally formed tubular shell (302) for supporting a plurality of independent satellites (340) thereon. The tubular shell (302) is significantly lighter than multi-piece dispenser shells that require a connecting ring for coupling the post portion and base portion of the shell together. The single piece shell (302) also significantly reduces the cost and simplifies the manufacture of the dispenser shell. The dispenser shell (302), in certain preferred embodiments, includes a tapered post portion (304) which enables satellites (340) being carried on the upper portion of the post portion to extend further into a fairing (342) disposed over the satellites (340) and dispenser shell (302) during flight, thus making more efficient use of the envelope defined by the interior area of the fairing (342). A frusto-conical base portion (306) integrally formed with the post portion (304) enables the load supported by the dispenser shell (302) to be evenly distributed throughout the base portion (306). The single-piece design also significantly improves the bending stress resistance of the dispenser and its overall structural rigidity. The various preferred embodiments each include a plurality of circular frames which are secured to an interior surface of the dispenser shell. A plurality of interface fittings are secured to an exterior surface of the dispenser shell and support a plurality of satellites thereon.
