可分解金属锥形件及其制造方法和使用
摘要：
一种截锥形部件，其包括金属复合物，该金属复合物具有包括金属纳米基体材料的多孔纳米基体；设置在多孔纳米基体中的金属基体；以及第一截锥部。一种制造所述截锥形部件的方法，包括将金属基体粉末、分解剂和金属纳米基体材料组合形成组合物；将所述组合物压实以形成压实的组合物；烧结压实的组合物；以及压制烧结的组合物以形成所述截锥形部件，该截锥形部件的外表面上具有锥形部。所述截锥形部件可以通过下述方式使用：使该截锥形部件的截锥部与一物品的锥形表面接触；向所述截锥形部件施加压力；相对于所述物品沿着使所述物品的径向尺寸膨胀的方向压迫所述截锥形部件；以及使所述截锥形部件与用于分解所述截锥形部件的流体接触。
摘要（英）：

A frustoconical member includes a metal composite that has a cellular nanomatrix comprising a metallic nanomatrix material; a metal matrix disposed in the cellular nanomatrix; and a first frustoconical portion. A process of making the frustoconical member includes combining a metal matrix powder, a disintegration agent, and metal nanomatrix material to form a composition; compacting the composition to form a compacted composition; sintering the compacted composition; and pressing the sintered composition to form the frustoconical member having a tapered portion on an outer surface of the frustoconical member. The frustoconical member can be used by contacting a frustoconical portion of the frustoconical member to a tapered surface of an article; applying pressure to the frustoconical member; urging the frustoconical member in a direction relative to the article to expand a radial dimension of the article; and contacting the frustoconical member with a fluid to disintegrate the frustoconical member.
