    • A process of making a vane for a rotary expansible chamber device, comprising the steps of: providing an open vane die having a die cavity, wherein said die cavity comprises a body cavity section corresponding to a body of the vane, a first tip cavity section corresponding to a first tip of the vane, and a second tip cavity section corresponding to a second tip of the vane; providing a preheated, porous carbon preform in the first tip cavity section of the vane die, the preform having a shape corresponding to at least a portion of the first tip cavity section; closing the vane die; injecting a castable admixture comprising a metal alloy and a plurality of inorganic particles into the die cavity and filling the vane die cavity with the injected admixture; impregnating the preform with the metal alloy of the injected admixture, substantially all of the inorganic particles from the injected admixture being filtered out by the preform as the admixture flows into the preform; allowing the castable admixture to solidify, whereby a vane is formed in the die cavity; and removing the vane from the die.
    • 一种制造用于旋转可膨胀室装置的叶片的方法,包括以下步骤:提供具有模腔的开式叶片模头,其中所述模腔包括对应于叶片主体的体腔部分,第一尖端腔部分 对应于所述叶片的第一末端,以及对应于所述叶片的第二尖端的第二末端腔部分; 在所述叶片模具的所述第一尖端腔部分中提供预热的多孔碳预制件,所述预成型件具有对应于所述第一末端腔部分的至少一部分的形状; 关闭叶片模具; 将包含金属合金和多个无机颗粒的可浇铸混合物注入模腔中并用注入的混合物填充叶片模腔; 用注入的混合物的金属合金浸渍预型体,当混合物流入预制件时,基本上所有来自注入的混合物的无机颗粒被预成型件过滤掉; 允许浇注混合物固化,由此在模腔中形成叶片; 并从模具中移除叶片。
