Abstract: The present invention provides a process for the application of high temperature coating that provide enhanced impact resistance and erosion damage for the coatings. For high temperature coating systems that provide environmental protection to silicon based ceramics, the process provides the deposition of a silicon-based bond coat on the substrate using the directed vapor deposition with plasma activation and at least one supersonic gas jet nozzle. The process provides the deposition of an EBC layer using the directed vapor deposition with the gas jet nozzle. In one embodiment, the thermal barrier layer may also contain one or more dense embedded layers which further promote impact resistance. Within the process, the particular layers, silicon bond coat, EBC layer and/or TBC layer may be deposited together or specific novel layers applied in combination with other layers deposited using prior known deposition techniques.

Abstract: The present invention provides for a method and apparatus for the directed vapor deposition (DVD) on non-line of sight (NLOS) portions of a substrate. The method and apparatus includes evaporating a first material for deposition on to the substrate, the evaporating generating a plurality of vapor molecules.

One embodiment utilizes plasma activation to ionize the vapor particles and bias the substrate to attract the charged vapor molecules onto the NLOS portion. Another embodiment uses an inert gas as the carrier gas. Another embodiment includes pre-heating the carrier gas prior to its insertion into the deposition chamber. Whereby the varying embodiments and combinations herein improve NLOS DVD.

Abstract: The present inventions incorporate self-healing mechanisms into current and future EBC systems. Such approaches have the potential to form environmental protection materials (i.e. thermally grown silicate compositions) in-situ to enable the ability to provide environmental protection to SiC based ceramics even in the event that cracks or voids form from within the EBC layer. In this disclosure, novel, self-healing EBC systems are disclosed along with coating synthesis techniques required to deposit the materials, microstructures and architectures. This research is anticipated to result in a thermal/environmental barrier coating system (T/EBC) that provides improved durability over current coatings. These advancements will aid the use of Si-based ceramics in a range of high temperature applications such a gas turbine engines and heat exchangers. These advances will not only benefit military engines, but also commercial and industrial engines requiring greater performance.

Abstract: Depositing pure aluminum and aluminum alloy coatings onto substrates using directed vapor deposition (DVD) method is presented herein. The aluminum alloys have decreased environmental impact both due to their composition and due to the use of DVD process with no hazardous precursors or waste. Corrosion resistance of DVD deposited aluminum and aluminum alloys is effective for protection of steel substrates. The invention includes the use of the DVD technique to apply aluminum and/or aluminum alloy coatings effective for corrosion protection; the use of plasma-activated DVD to enhance the density of aluminum and aluminum alloy coatings deposited at low substrate temperatures; the use of multi-source evaporation to control composition of aluminum alloys during DVD deposition; the application of aluminum and/or aluminum alloy coatings onto NLOS substrates can be used for corrosion protection.

Abstract: Presented are nano-composite coatings to improve wear and corrosion resistance of high-strength steel parts or other substrate including the non-line-of-sight (NLOS) regions thereof. The disclosed nano-composite coatings are shown to have a 3x to 5x improvement in wear rate compared to hard chrome. The invention includes the use of the directed vapor deposition (DVD) technique to deposit nano-composite coatings to substrates. Also presented are nano-composite coatings applied in layers of film of differing thickness and composition. Wear of the layers of film and thus, remaining life of the coating may be determined by resistance or spectroscopy.

The vapor flux is directed toward the filament via a carrier gas in a coating chamber under vacuum. The carrier gas can substantially surround the vapor flux as the filament is exposed to a coating material comprised by the vapor flux. Wherein the filament moves relative to the vapor flux.
