  • Publication number: 20140044991
    Abstract: Superalloy component castings, such as turbine blades and vanes, are fabricated or repaired by an electroslag or electrogas welding process that at least partially replicates the crystal structure of the original cast substrate in a cast-in-place substrate extension. The process re-melts the base substrate surface and grows it with new molten filler material. As the base substrate and the filler material solidify, the newly formed “re-cast” component has a directionally solidified uniaxial substrate extension portion that at least in part replicates the crystalline structure of the base substrate. The “re-cast” component can be fabricated with a unified single crystal structure, including the extension portion. In other applications, a substrate extension can replicate a directionally solidified uniaxial crystal structure of an original base substrate casting.

The evaporative material is typically foam polystyrene. The strength of the foam polystyrene is low. Since the reinforcing member which is made of a material having strength higher than that of the evaporative material is embedded in the evaporative pattern 102 which is made of the foam polystyrene, the strength of the evaporative pattern 102 improves.

  • Publication number: 20130260178
    Abstract: Metallic components, including superalloy components such as turbine vanes and blades, are joined or repaired by electric resistance with a high electrical resistivity brazing alloy composition. In some embodiments the brazing alloy comprises filler metal selected from the group consisting of nickel, iron, and cobalt base alloy and elements selected from the group consisting of phosphorous (P), boron (B), silicon (Si), germanium (Ge), sulfur (S), selenium (Se), carbon (C), tellurium (Te) and manganese (Mn). In performing the method of the present invention a high electrical resistivity brazing alloy composition is introduced within a substrate defect or interposed between two substrates that are to be joined. An electric current is passed through the brazing alloy until the alloy melts and bonds to the adjoining substrate. High resistivity of the brazing alloy concentrates heat generated by the current flow in the brazing alloy rather than in the substrate.

    Abstract: A multi-layer coating for a smooth contact surface of a clutch plate and a method for manufacturing the same have been developed. This coating can help reduce the prevalence of clutch shudder, noise, and plate wear that is often encountered in a friction-disc clutch mechanism found in a motor vehicle's powertrain. The multi-layer coating may comprise a relatively soft base layer and one or more relatively hard particle layers overlying the base layer. This combination of layers can help provide stable friction characteristics and thermal properties between clutch plate surfaces. One or more optional bonding layers may also be provided between any two adjacent layers to improve the adherent bonding therebetween. At least some of the layers of the multi-layer coating may be applied by a HVO/AF thermal spray procedure.

  • Publication number: 20110284666
    Abstract: According to a laser welding method, an inert gas injection process and welding process are performed. In the inert gas injection process, inert gas is injected into an inside of a first metal pipe; and air inside the first pipe is discharged into the outside. In the welding process, a second metal pipe is irradiated with a laser from radially outward of the second pipe; metal is melted with a penetration depth of a penetration part adjusted such that a leading end of the penetration part is located within thickness of the first pipe; and the first and second pipes are welded together along the circumferential direction to form a pipe joint product. An inner wall of the first pipe maintains its pre-welding metallic luster. An injector includes an injection nozzle, a fuel passage member, a valve member accommodated in the fuel passage member, and a driving unit driving the valve member.

  • Publication number: 20110280732
    Abstract: A material is diffused into an electrically conductive substrate to enhance and add desirable properties through a metalliding process employing an electrolytic bath within an atmosphere substantially free of oxygen. The substrate to be coated is submerged within the bath as a cathode along with multiple anodes, each anode having a distinctive composition from the other. A variable power source provides preselected current densities to each of the anodes so as to result in a diffusing of material from each anode for coating the substrate in proportion to the current densities applied to each anode. Products of the invention include an electrically conductive substrate and an alloy coating diffused into a surface of the substrate, wherein the alloy coating comprises a compound of beryllium, boron or silicon, plus at least one refractory metal.

  • Patent number: 8039119
    Abstract: Orientation degree and smoothness of a substrate surface better than those of conventional ones are provided in a textured substrate for epitaxial thin film growth. The present invention is a textured substrate for epitaxial film formation, including a crystal orientation improving layer made of a metal thin film of 1 to 5000 nm in thickness on the surface of the textured substrate for epitaxial film formation having a textured metal layer at least on one surface, wherein differences between orientation degrees (?? and ??) in the textured metal layer surface and orientation degrees (?? and ??) in the crystal orientation improving layer surface are both 0.1 to 3.0°. Further, when another metal different from the metal constituting this textured substrate crystal orientation improving layer is added equivalent to a thin film which is 30 nm or less, and subsequently is subjected to heat treatment, the smoothness of that surface can be improved.
