Abstract:
A composite component and a plated polymer component are disclosed. The composite component may comprise a body portion formed from an organic matrix composite, a first metal coating applied to a surface of the body portion, and an outer metal layer on the first metal coating that is erosion-resistant. The plated polymer component may comprise a polymer substrate, a metal plating layer applied to a surface of the polymer substrate, and at least one selectively thickened region in the metal plating layer. The at least one selectively thickened region may assist in protecting the plated polymer component against wear and/or erosion.
Abstract:
Methods for repairing plated metallic layers on plated polymeric parts are disclosed. First, a polymer is formed into an article of a desired shape or geometry. The outer surface of the article is prepared to receive a catalyst and then the outer surface is activated with the catalyst. A first metallic layer is then plated onto the outer surface to form a structure. Optional additional metallic layers may be applied. Then, a defect in a damaged metal layer is repaired by brush plating or brush electroplating.
Abstract:
An abrasive coating for a substrate comprises a strike layer is formed on a substrate top surface; a base layer is coupled to the strike layer; a tack layer is coupled to the base layer, wherein the tack layer is configured to adhere first grit particles to the base layer; a plurality of first grit particles are adapted to be coupled to the tack layer, a plurality of second grit particles are placed between each of the plurality of first grit particles, the second grit particles having a nominal size smaller than the first grit particles; and an overplate layer comprising a matrix material is bonded to the tack layer; the matrix material envelops the second grit particles and bonds and partially surrounds the first grit particles, wherein the first grit particles extend above the overplate layer.

Abstract:
A method for balancing a rotatable component is disclosed This method comprises and then plating the component to deposit a metal layer onto the component until the component is balanced. In addition, and alternative method for balancing a rotatable component is disclosed. This method comprises attaching a balancing weight to the rotatable component and rotating the component. This is followed by plating the component and the balancing weight to deposit a metal layer onto the balancing weight and the component until the component is balanced.
Abstract:
An article comprises: a substrate having a matrix and a plurality of metallic members partially embedded in the matrix; and a metallic layer bonded to exposed portions of the metallic members.
Abstract:
Plated polymeric gas turbine engine parts and methods for fabricating lightweight plated polymeric gas turbine engine parts are disclosed. The parts include a polymeric substrate plated with one or more metal layers. The polymeric material of the polymeric substrate may be structurally reinforced with materials that may include carbon, metal, or glass. The polymeric substrate may also include a plurality of layers to form a composite layup structure.
Abstract:
A method for fabricating a ceramic component is disclosed. The method may comprise: 1) forming a polymer template having a shape that is an inverse of a shape of the ceramic component, 2) placing the polymer template in a mold; 3) injecting the polymer template with a ceramic slurry, 4) firing the ceramic slurry at a temperature to produce a green body, and 5) sintering the green body at an elevated temperature to provide the ceramic component.
