    摘要: Particles of metal alloys and composites have been developed that are particularly suitable for use in producing thixotropic alloys and in the injection molding of such alloys. The particulate material comprises particles of metal alloy or composite, wherein a substantial proportion of the particles is shaped such that the ratio of the length of the largest dimension of a particle to the effective diameter of the particle is in the range of 1.0 to 4.0 and the substantial proportion of particles has a particle size wherein the largest dimension of the particles lies within the range of 0.5 to 5.0 mm. This allows convenient handling of the particles whilst also avoiding binding or clogging of the screw, in the case where a screw extruder is used.

    摘要: An improved method of applying a particulate material to a substrate, includes the steps of: removing impurities from a surface of the substrate; forming a coating composition having a bonding material and at least one particulate material; applying the coating composition to the substrate surface; and creating a diffusion bond between the substrate, bonding material and particulate material for generating a continuous interface between the substrate surface and particulate material such that the change in mechanical properties between the substrate and particulate material occurs in a direction normal to the plane of the substrate surface, thereby minimizing residual strain and coefficient of thermal expansion mismatch between the substrate and particulate material, the surfaces of individual particles of said particulate material being chemically wetted by the bonding material. The particulate material and the bonding material comprise a layer on the substrate surface.

    摘要: In a method for injection molding of metallic mixtures, a metallic substance with a high melting point is mixed with a metallic substance having a lower melting point that serves in part as a binder material, and the mixture may be blended to form a homogenous feedstock for injection molding, or the mixture may be introduced directly into an injection molding apparatus.
