  • Patent number: 9090515
    Abstract: A method for repairing an open shrinkage crack in a concrete slab employs expansive mortar. A saw cut is created next to the shrinkage crack, and then expansive mortar is applied into the open saw cut. The expansive mortar material gradually expands and urges the saw cut apart. This shifts the portion of the slab between the saw cut and the slab in the direction to close the shrinkage crack tightly. The expanded mortar material is removed from the saw cut and a rigid spacer is installed in the saw cut. An adhesive can be installed between the two sides of the crack. The surface of the repaired slab can be given cosmetic repairs, and let dry before applying a sealer.

  • Publication number: 20140030464
    Abstract: A turbine repair process, a repaired coating, and a repaired turbine component are disclosed. The turbine repair process includes providing a turbine component having a higher-pressure region and a lower-pressure region, introducing particles into the higher-pressure region, and at least partially repairing an opening between the higher-pressure region and the lower-pressure region with at least one of the particles to form a repaired turbine component. The repaired coating includes a silicon material, a ceramic matrix composite material, and a repaired region having the silicon material deposited on and surrounded by the ceramic matrix composite material. The repaired turbine component a ceramic matrix composite layer and a repaired region having silicon material deposited on and surrounded by the ceramic matrix composite material.

  • Publication number: 20140030465
    Abstract: Technologies described herein are generally related to repairing graphene on a porous support. In some examples, a method is described that may include receiving a graphene layer on a support. The graphene layer may include a hole and a pore. The method may further include applying a first reactive material to a first side of the graphene layer. The first reactive material may include molecules larger than the pore. A second reactive material may be applied through the support to a second side of the graphene layer. The second reactive material may include molecules larger than the pore. The first and second reactive materials may react in the hole to produce a plug in the hole and to repair the graphene layer.

  • Publication number: 20130337215
    Abstract: A used component, such as an engine block or engine head, has at least one dimension that does not match a dimensional specification for the component. A thermal spray coating of FeAlSiC is applied to build up the dimension. The excess coating is milled off so that the body and coating have a second shape that matches the dimensional specification for the component. The coating has an ordered DO3 crystal structure with a stable aluminum oxide scale that produces oxidation resistance at about 700° C.

  • Patent number: 8524356
    Abstract: A composite laminate patch for reworking an inconsistent area in a structure has inner and outer control regions possessing differing interlaminar fracture toughnesses for controlling the advance of a disbond in the patch. One or more separation zones in the patch between the control regions aids in diffusing the fracture energy of the disbond as the disband advances from the inner region to the outer region.

  • Patent number: 8511029
    Abstract: This invention is a method and apparatus for repairing a hole in a surface with a perforated repair patch. The repair patch, which is affixed to and substantially cover over the hole, is indented inwards by applying cement compound into its perforations and pushing the repair patch into the hole as the cement compound hardens. A layer of drywall compound is then applied over the indented repair patch to smooth it with the rest of the wall. The perforated repair patch may include an additional layer of mesh sheet material to minimize cracking of the drywall compound.

    Abstract: A method for fabricating a repair laminate for a composite part having an exposed surface includes applying a release film to the exposed surface and forming an uncured ply stack assembly on the release film. The uncured ply stack assembly is formed by forming and compacting a series of uncured ply stacks. The release film and ply stack assembly is then removed from the exposed surface. A bonding material is then applied to the exposed surface, and the uncured ply stack assembly is applied to the bonding material. The ply stack assembly and bonding material are then cured.
