  • Patent number: 10583528
    Abstract: A process is described for laser welding a sheet metal workpiece having an anti-corrosion pre-coat on at least one major surface thereof and having first and second opposite side edges. The sheet metal workpiece is arranged such that the first and second side edges are in contact with one another and such that the at least one major surface faces outwardly. A laser beam having a first beam spot-size, is used to form a laser weld joint between the first and second side edges. Subsequently, a localized anti-corrosion surface layer is formed on the laser weld joint. To this end, a laser beam having a second beam spot-size larger than the first beam spot-size is scanned along the laser weld joint. During the scanning, a flow of a powdered anti-corrosion surface layer material is directed toward a portion of the laser weld joint that is being irradiated by the laser beam. The laser beam melts the material, which subsequently solidifies to form a layer adhering to the laser weld joint.

    Abstract: Functionally graded materials can be prepared through additive manufacturing by determining the path that a head of 3D printer can follow while extruding a material mix of a required composition at required points of a layer of an FGM. Each point within the layer is evaluated regarding the directions within which the printing head can move into from that point while extruding the material mix of a required composition. Based on the evaluation, a multitude of polygons are defined within the polygonal shape that are guaranteed to be printable. A path can be designed for the printing head to follow to print all of the defined polygons, and consequently, to print the entire polygonal layer. Material extrusion commands are generated for the printing head.

  • Publication number: 20140248512
    Abstract: A method of repairing or manufacturing a superalloy component (50) by depositing a plurality of layers (22, 24, 26, 28) of additive superalloy material having a property that is different than an underlying original superalloy material (30). The property that is changed between the original material and the additive material may be material composition, grain structure, principal grain axis, grain boundary strengthener, and/or porosity, for example. A region (60) of the component formed of the additive material will exhibit an improved performance when compared to the original material, such as a greater resistance to cracking (58).

    Abstract: Recoating process and recoated turbine blade are disclosed. The recoating process includes providing a coated turbine blade, then removing a portion of the thermal barrier coating system to form a partially-stripped turbine blade, then applying a bond recoat to the stripped region of the partially-stripped turbine blade; and then applying a thermal barrier recoat to the bond recoat to form a recoated turbine blade. The recoated turbine blade comprises the bond coating portion abutting the bond recoat, the thermal barrier coating portion abutting the thermal barrier recoat, and the stepped configuration. The coated turbine blade has a thermal barrier coating system positioned on a substrate. The partially-stripped turbine blade has a stripped region, a bond coating portion, a thermal barrier coating portion, and a stepped configuration.

  • Patent number: 8741381
    Abstract: A method for controlled removal of a portion of a diffusion coating from a coated superalloy component and a method for rejuvenating a coated superalloy component are provided. The methods include providing the component having an oxide layer, an additive layer between the oxide layer and a diffusion zone, the diffusion zone being between the additive layer and a superalloy substrate of the superalloy component. The methods include selectively removing the oxide layer and a portion of the additive layer by grit blasting, wherein removing creates an exposed portion. Rejuvenating includes applying an aluminide coating to the exposed portion and heat treating at a preselected elevated temperature to form a rejuvenated protective aluminide coating on the superalloy component.

  • Patent number: 8722144
    Abstract: A thermal barrier coating method forms a thermal barrier coating by spray coating over the surface of a component where cooling holes are made. The thermal barrier coating is formed by spray coating after masking pins, which do not protrude above the surface of the component, are inserted into the cooling holes or masking pins protruding above the surface of the component are inserted and get shrunk due to heat while spray coating, obtaining the protruding amount equal to or less than the thickness of the thermal barrier coating after shrinkage, which characterizes the method. By way of this method, a thermal barrier coating can be formed all over the surface without clogging the cooling holes.
