    摘要： A process and device in production of precise three-dimensional sinters of a shape substantially close to that of an original part, using flash sintering produced by spark plasma sintering (SPS) technology. A mold is produced in a die of an enclosure for SPS flash sintering, the mold being shaped as an impression of the original part. The following are deposited in successive layers in the mold: a layer based on a superalloy powder, a metallic protection layer, and a thermal barrier layer. In a sintering, pressurization is initiated and a pulsed current passes through, producing a rapid rise in temperature in accordance with a flash sintering cycle whose temperature, pressure, and duration are regulated, with at least one temperature plateau and one pressure plateau. The layer of superalloy forms, by diffusion, during the sintering, a bonding continuum of material with the part to be repaired.

    摘要： A composite steel plate in which at least two steel sheets are rolled to form a plate. One of the sheets has a composition that varies in a depthwise direction between nanocrystalline and micron grained. The plate is made by treating a steel sheet to produce a composition in the sheet that varies in a depthwise direction of the sheet between nanocrystalline and micron grained, stacking the treated sheet with at least one other steel sheet and rolling the sheets to form the plate.

    摘要： The tool has a clamping part (2) and a working part (11). It consists of a wear-resistant material, which contains tungsten carbide which has a grain size that lies in the range between approximately 0.2 and approximately 0.5 μm. The clamping part (2) consists of a tough material, which likewise contains tungsten carbide which has a grain size in the range between approximately 0.8 and approximately 1.3 μm. In a transitional region (11) between the working part (11) and the clamping part (2), the proportion of wear-resistant tungsten carbide decreases in the direction of the clamping part (2) to 0 and the proportion of tough tungsten carbide decreases in the direction of the working part (11) to 0. The mixing ratio between wear-resistant and tough tungsten carbide changes approximately steadily in the transitional region (10).

    摘要： A structural component suitable for use as refinery and/or petrochemical process equipment and piping is provided. The structural component has improved corrosion, abrasion, environmental degradation resistance, and fire resistant properties with a substrate coated with a surface-treated amorphous metal layer. The surface of the structural component is surface treated with an energy source to cause a diffusion of at least a portion of the amorphous metal layer and at least a portion of the substrate, forming a diffusion layer disposed on a substrate. The diffusion layer has a negative hardness profile with the hardness increasing from the diffusion surface in contact with the substrate to the surface away from the substrate.
