Abstract: A metal microparticle coated with metal hydride nanoparticles is disclosed. Some variations provide a material comprising a plurality of microparticles (1 micron to 1 millimeter) containing a metal or metal alloy and coated with a plurality of nanoparticles (less than 1 micron) containing a metal hydride or metal alloy hydride. The invention eliminates non-uniform distribution of sintering aids by attaching them directly to the surface of the microparticles. No method is previously known to exist which can assemble nanoparticle metal hydrides onto the surface of a metal microparticle. Some variations provide a solid article comprising a material with a metal or metal alloy microparticles coated with metal hydride or metal alloy hydride nanoparticles, wherein the nanoparticles form continuous or periodic inclusions at or near grain boundaries within the microparticles.

Abstract: A metal microparticle coated with metal nanoparticles is disclosed. Some variations provide a material comprising a plurality of microparticles (1 micron to 1 millimeter) containing a metal or metal alloy and coated with a plurality of nanoparticles (less than 1 micron) or nanoparticle inclusions (potentially larger than 1 micron). The invention eliminates non-uniform distribution of sintering aids by attaching them directly to the surface of the microparticles. No method is previously known to exist which can assemble nanoparticle inclusions onto the surface of a metal microparticle. Some variations provide a solid article comprising a material with a metal or metal alloy microparticles coated with metal hydride or metal alloy nanoparticles, wherein the nanoparticles form continuous or periodic inclusions at or near grain boundaries within the microparticles.

Abstract translation: 公开了涂覆有金属氢化物纳米颗粒的金属微粒。 一些变型提供了包含多个含有金属或金属合金的微粒（1微米至1毫米）并涂覆有含有金属氢化物或金属合金氢化物的多个纳米颗粒（小于1微米）的材料。 本发明通过将它们直接附着在微粒的表面上来消除烧结助剂的不均匀分布。 以前不知道存在可以将纳米颗粒金属氢化物装配到金属微粒表面上的方法。 一些变型提供了一种固体制品，其包括具有用金属氢化物或金属合金氢化物纳米颗粒涂覆的金属或金属合金微粒的材料，其中纳米颗粒在微粒内或其附近的晶界处或附近形成连续或周期性的夹杂物。
