摘要： Disclosed is a process for manufacturing a sintered slide bearing. A sintered porous bearing body is prepared from a powdered metal material and a resin material in a fluidable state is penetrated into the sintered porous bearing body. The resin material in the sintered porous bearing body is hardened, and the sintered porous bearing body after the hardening of the resin material is repressed to reduce a gap produced between the sintered porous bearing body and the hardened resin material by volume reduction caused on the resin material at the hardening.

摘要： Near-net-shape soft magnetic components can be produced from iron powder-lubricant compositions using powder metallurgy techniques. The resulting components have isotropic magnetic and thermal properties and may be shaped into complex geometry using conventional compaction techniques. A non-coated ferromagnetic powder is mixed with a lubricant and compacted. After compaction, the components are thermally treated at a moderate temperature to burn out the lubricant, and possibly also relieve the stresses induced during pressing and reduce the hysteresis losses. Depending on the application, the properties of the material may be tailored by varying the content and type of the lubricant and the thermal treatment conditions.

摘要： In infiltrating a porous metal skeleton an infiltrant composition is used similar to that of the powder skeleton, but with the addition of a melting point depressant. The infiltrant quickly fills the skeleton. As the melting point depressant diffuses into the base powder, the liquid may undergo diffusional solidification and the material eventually homogenizes. Maintaining the infiltrant at a liquidus composition for the infiltration temperature typically ensures that the bulk composition or properties will remain uniform throughout the part, particularly in the direction of infiltration. Success of such an infiltration is enhanced by effective means of maintaining the molten infiltrant at a liquidus composition. It is also beneficial, in some cases, for the time scale of the infiltration to be much faster than the time scale of the diffusion of the melting point depressant and the subsequent solidification and homogenization. The relative rates of infiltration and diffusion/solidification rate are significantly impacted by the choice of materials system. Other factors also influence these rates. They include: selection of powder size (diameter), shape, surface roughness, and size distribution, feeding liquid from different locations, liquid feeder channels, smoothing of the part surface with fine powder and affecting infiltrant fluid properties. Various material systems are also disclosed, as are methods of designing a process of infiltrating a part, including binary and ternary and higher component systems. Homogeneous composition may be achieved using these techniques, particularly along the direction of infiltration.
摘要翻译：在渗透多孔金属骨架时，使用类似于粉末骨架的浸润剂组合物，但加入了降低熔点的组合物。渗透剂快速填满骨架。当熔点降低剂扩散到基础粉末中时，液体可能经历扩散凝固，并且材料最终均匀化。为了渗透温度将浸润剂维持在液相线组合物上通常确保整个组分或性质在整个部分，特别是在渗透方向上保持均匀。通过将熔融浸润剂保持在液相组成的有效手段来增强这种浸渗的成功。在某些情况下，渗透的时间尺度比熔点抑制剂的扩散时间尺度和随后的凝固和均化也快得多也是有益的。渗透和扩散/凝固速率的相对速率受材料体系选择的影响很大。其他因素也影响这些利率。它们包括：选择粉末尺寸（直径），形状，表面粗糙度和尺寸分布，从不同位置输送液体，液体进料通道，用细粉进行部分表面的平滑处理并影响浸润液的性质。还公开了各种材料系统，以及设计渗透部件的方法的方法，包括二元和三元和更高分量系统。使用这些技术可以实现均匀组合，特别是沿渗透方向。

摘要： A powder injection molding and infiltration process. A powder of a skeleton material having a relatively high melting point is mixed with a composite binder to form a mold mixture. The composite binder is comprised of at least two binder materials. The mold mixture is molded into a desired shape in a mold device to produce a molded part. The composite binder is then removed to produce voids in the molded part and the voids are filled by infiltrating an infiltrant comprised of an infiltrant material having a relatively low melting point to produce a composite molded part. In a preferred embodiment the skeleton material is TiB2 and the infiltrant material is aluminum and the composite binder is comprised of a plastic and a wax. In this embodiment the wax portion of the composite binder is removed using a solvent and the plastic is removed during the infiltration step. The resulting composite part has a TiB2 skeleton with voids substantially filled with aluminum. This process is especially useful for making light and strong parts with complex shapes such as golf club heads, tools, cutting implements, thermal management products, rocket motor components and bicycle parts. In another preferred embodiment, a golf club head is comprised of three parts: an non-sintered TiB2 part for the body of the head, a sintered TiB2 part for the striking surface of the head, and a heavy tungsten part to provide weight for the head. In this embodiment, the aluminum infiltrant substantially fills the voids in all three parts to create a golf club head with optimum characteristics.

摘要： A process for preparing complex-shaped, ceramic-metal composite articles, comprising: (a) contacting a non-wettable powder that is non-wetting to a metal to be used for infiltration with a shaped ceramic body to form a layer of the non-wettable powder on one or more surfaces of the shaped ceramic body, wherein the shaped ceramic body has a region where there is no layer of the non-wettable powder, and (b) infiltration the shaped ceramic body with the metal through the region or regions where there is no layer of the non-wettable powder, such that a complex-shaped ceramic-metal composite comprising one or more metal phases and one or more ceramic phases is formed, wherein the article has substantially the net shape of the shaped ceramic body and undesirable regions of excess metal on the surface and undesirable phases within the complex-shaped ceramic-metal composite article near the surface are located only in the region or regions where there is no layer of the non-wettable powder. The process of the invention allows the preparation of complex-shaped ceramic-metal composite articles with undesirable regions of excess metal and undesirable phases on the surface(s), of, or within, the article only in the regions where there is, or was, no layer of non-wettable powder. The process of the invention allows the preparation of a complex-shaped ceramic-metal composite article which requires little or no machining of the surface(s) to achieve a finished article. A complex-shaped ceramic-metal composite article is prepared which contains few undesirable regions of excess metal and undesirable phases.
