Coating system and method
Systems and methods that provide or restore a coating to a component are provided. The systems and methods utilized an atomizing spray device. A slurry that comprises a fluid and ceramic particles, and a gas are supplied to the atomizing spray device. The slurry and gas are discharged from the spray device to form two-phase droplets. The fluid within the droplets evaporates to prevent the fluid from becoming part of the coating as the droplets traverse through the air and prior to impacting the surface of the component.
CANDY COLOR PAINT AND REFINISHING METHOD
Candy color metallic paint finishes can be formed or repaired by applying to a substrate a colored liquid base coating composition containing a colored metal oxide-coated nontransparent silver dollar aluminum flake pigment and optional additional colored pigments or dyes dispersed in a first hardenable binder to form a reflective colored base layer that hides the primed substrate and has a sparkling metallic appearance. A colored liquid intermediate coating composition containing a colored pigment or dye dispersed in a second hardenable binder is applied to the base layer to form a colored intermediate layer that increases the color saturation of incident light reflected from the base layer. The intermediate layer can be overcoated with a liquid clearcoat composition. The completed finish can replicate an original equipment manufacturer multilayer candy color metallic finish, while providing ease of application, low sensitivity to layer thickness variation, and low mottle.
Filled composition with rapid UV cure to form thick coating
A composition is provided that includes aliphatic urethane acrylate; a multifunctional crosslinking agent; photoinitiator; a chemical initiator system of a peroxide or azo group containing catalyst, and a cure promoter; and a particulate filler. The composition is amenable to rapid cure to a sandable condition as compared to conventional products. By adjusting the amount of particulate filler present, a product is provided that operates as a primer, a putty, or a filler. A method of vehicle body repair includes the application of an uncured layer of the composition to the vehicle body. The uncured layer is exposed to UV radiation to induce cure of the uncured layer to form a coating in a time of between 2 and 20 minutes even with an ultraviolet wavelength emitting light emitting diode (UV LED).
REPAIR METHODS FOR SILICON-BASED COMPONENTS
A method for forming a patch repair on a silicon-based component is disclosed. The method includes applying a patch on a damaged area of a silicon-based component, drying the patch to form a dried patch, and sintering in situ the dried patch to form a patch repaired portion of the silicon-based component. The patch includes a patching material and the patching material includes a plurality of nanoparticles having a median particle size less than 100 nanometers. The plurality of nanoparticles includes at least one of silicon, silicon alloy, silica, or a metal silicate.
Adaptable surface treatment repair system
A surface treatment repair assembly for applying a surface treatment to a contoured surface includes an attachment device configured to removably attach to the contoured surface and a robotic unit is coupled to the attachment device. Furthermore, a treating unit is operably mounted on the robotic unit and including a plurality of applicator heads forming a treatment array and each applicator head is configured to apply a surface repair treatment. At least one sensor is mounted on the treating unit and configured to identify a target area for the surface repair treatment and a controller is operably coupled to the robotic unit and the treating unit. The controller is programmed to control a movement of the robotic unit to position the treatment array adjacent to the target area and to selectively operate the treatment array to apply the surface repair treatment on the target area of the contoured surface.
Localized atmospheric laser chemical vapor deposition
An atmospheric, Laser-based Chemical Vapor Deposition (LCVD) technique provides highly localized deposition of material to mitigate damage sites on an optical component. The same laser beam can be used to deposit material as well as for in-situ annealing of the deposited material. The net result of the LCVD process is in-filling and planarization of a treated site, which produces optically more damage resistant surfaces. Several deposition and annealing steps can be interleaved during a single cycle for more precise control on amount of deposited material as well as for increasing the damage threshold for the deposited material.
COATING ADHESION PROMOTORS AND METHODS OF USING THE SAME
Coating adhesion promotors and methods of coating a substrate are provided. In an exemplary embodiment, a method of coating a substrate includes applying an adhesion promotor over a primer, where the primer overlies the substrate. The adhesion promotor includes water. A first colored coat is applied over the adhesion promotor, and the first colored coat is flash dried. Tape is applied in a pattern over the first colored coat prior to the first colored coat fully curing. A second colored coat is applied over the first colored coat and over the tape, and the tape is removed from the first colored coat prior to the first colored coat fully curing.
MEMBER INSPECTION DEVICE AND MEMBER REPAIRING METHOD
In a member inspection device and a member repairing method, an irradiation device irradiates a surface of a member to be inspected with light, an image pickup device picks up an image of a surface portion irradiated with the light, a failure detection device detects a failure area on the basis of a photographed image picked up by the image pickup device, and a determining device classifies the shape of the failure area detected by the failure detection device.
LASER ANTI-SPATTER SLURRY OF RARE EARTH OXIDES
Methods for forming a hole in a coated component are provided. The method may include forming a sacrificial layer over a ceramic barrier coating of a substrate, drilling a hole into the coated component such that any spatter formed during drilling deposits onto the sacrificial layer, and removing the sacrificial layer along with the spatter deposited thereon. The sacrificial layer may include a rare earth oxide (e.g., rare earth oxide particles). Intermediate ceramic matrix composite (CMC) component are also provided. The intermediate CMC may include a CMC body, an environmental barrier coating on the bond coating, and a sacrificial layer on the environmental barrier coating, with the sacrificial layer including particles of a rare earth oxide dispersed in a polymeric matrix.
USE OF LOW-MOLECULAR CARBOXYLIC ACIDS IN AQUEOUS BASE COATS
Described herein is a method of using organic carboxylic acids having 1 to 10 carbon atoms in preparation of aqueous basecoat materials for the purpose of improving the adhesion of the aqueous basecoat materials to overbaked clearcoat materials. Also described herein is a method for producing a muilticoat paint system, where a basecoat material is applied directly to an overbaked clearcoat film.
