摘要： An apparatus and method are provided for coating particles in a rotating container. A cathode forms an electrically conductive inner surface of a side wall of the container. An anode is positioned relative to the cathode so as to permit both the cathode and the anode to be immersed together in an electrically conductive fluid. A motor is connected to the container and arranged to cause the container to rotate so as to generate a centrifugal force. Particles are placed in the container, the container is filled with the electrically conductive fluid, and electrical current is caused to pass from the cathode to the anode through the electrically conductive fluid while the container is rotated. The particles rest against the electrically conductive inner surface of the side wall of the container while the electrical current passes from the cathode to the anode, so as to result in deposition of a coating material from the electrically conductive fluid onto the particles.

摘要： A metallic composite solid, containing alloys and/or intermetallics, is formed by compacting at moderate pressure a mixture of powder particles, foils or sheets at a temperature close to room temperature, well below the melting temperature of the constituent components and without the addition of low melting metals such as mercury, indium or gallium acting as a sintering agent. This low temperature consolidation of the powder mixture is enhanced by having the surface oxide of the powder particles removed, prior to consolidation, and/or by coating the particles with an oxide-replacing metal such as silver or gold. The coating process may be replacement reactions, autocatalytic reduction or electrolytic reduction. The composite formation is assisted by the addition of a liquid acid such as fluoroboric acid, sulfuric acid, fluoric acid, adipic acid, ascorbic acid, or nitric acid. A preferred embodiment of the process for metal solid composite formation is a process for forming dental restorative materials at ambient temperatures and under pressure exerted by manual dental instrumentation.

摘要： A powder feed system for delivering a quantity of particulate material to a die cavity of a powder press is provided. The powder press has a table-like platen surface which is flush with and surrounds a die in which the die cavity sits, an upper punch appending from an upper ram and a lower punch. The powder feed delivery system includes a receptacle for receiving and delivering particulate material to the cavity. The receptacle has an ingress through which particulate material is received under pressure and an egress for registering with the interior of the cavity and through which particulate material is delivered under pressure from a feed conduit to the cavity. The feed conduit is attached at a first end to the receptacle ingress. At least one pressure generator is attached to a top end of a pressure vessel attached at a second end to the feed conduit. The pressure generator provides supra atmospheric pressure to push particulate material from the vessel into the die cavity when the die cavity is sealed from the atmosphere. The pressure generator is optionally used to fluidize the particulate material within the die cavity to create a substantially uniform density distribution of the particulate material within the cavity. At least one exhaust portal is provided for releasing pressure from within the die cavity.
