Chemical vapor deposition and powder formation using thermal spray with near supercritical and supercritical fluid solutions

A method for chemical vapor deposition using a very fine atomization or vaporization of a reagent containing liquid or liquid-like fluid near its supercritical temperature, where the resulting atomized or vaporized solution is entered into a flame or a plasma torch, and a powder is formed or a coating is deposited onto a substrate. The combustion flame can be stable from 10 torr to multiple atmospheres, and provides the energetic environment in which the reagent contained within the fluid can be reacted to form the desired powder or coating material on a substrate. The plasma torch likewise produces the required energy environment, but, unlike the flame, no oxidizer is needed so materials stable in only very low oxygen partial pressures can be formed. Using either the plasma torch or the combustion plasma, coatings can be deposited and powders formed in the open atmosphere without the necessity of a reaction chamber, but a chamber may be used for various reasons including process separation from the environment and pressure regulation.

본 발명은 열 분무 시스템 및 방법에 관한 것으로, 이는 스폿으로서 기판 표면상으로 돌출하는 가스 컬럼의 형태를 갖는 기판 쪽으로 가열된 가스를 가속시키는 노즐을 구비한 뜨거운 가스 발생기를 포함한다. 가스 컬럼 쪽으로 향한, 노즐 출구에 가장 가까운 하나 이상의 공급 원료 인젝터가 공급 원료 소스에 연결된다. 뜨거운 가스 스트림은 열과 운동량을 공급 원료에 옮겨서, 공급 원료 입자들이 기판과 충돌하게 함으로써 코팅을 형성한다. 이러한 시스템은 또한 축 쪽으로 향하고 액체의 소스에 연결된, 노즐 출구에 가장 가까운 하나 이상의 액체 인젝터를 포함한다. 이러한 시스템은 액체가 주입되는 흐름과 속도를 제어하여, 가스 컬럼 내로의 액체의 침투 깊이를 제어하는 것을 허용한다. 이러한 방법은 준최적 공급 원료 미립자가 기판에 부착되는 것을 선택적으로 방지하고, 준최적 침전물의 원 위치에서의 제거를 제공한다. The present invention relates to a thermal spray system and method comprising a hot gas generator having a nozzle for accelerating heated gas towards a substrate having the form of a gas column projecting onto a substrate surface as a spot. One or more feedstock injectors closest to the nozzle outlet, directed towards the gas column, are connected to the feedstock source. The hot gas stream transfers heat and momentum to the feedstock, causing the feedstock particles to collide with the substrate, forming a coating. Such a system also includes one or more liquid injectors proximate to the nozzle outlet, axially directed and connected to a source of liquid. Such a system allows controlling the depth of penetration of the liquid into the gas column by controlling the flow and rate at which the liquid is injected. This method selectively prevents sub-optimal feedstock particulates from adhering to the substrate and provides in situ removal of sub-optimal deposits.

The voids provide nucleated boiling sites for a liquid heated by the surface.

Coatings, particularly thin films, of polymeric material are produced in accordance with the invention by applying a finely divided aerosol of polymer solution to a substrate and substantially simultaneously applying an energy source to the applied solution to apply the solution. In cases where the polymer is cross-linking, the energy source assists in cross-linking of the polymer. The preferred energy source is a flame that may optionally or desirably deposit material along with the polymer spray. One particular aspect of the invention is directed to production of polyimide films. In accordance with another aspect of the invention, the co-deposition process is used to provide thin polysiloxane coatings on glass and other substrates.

Chemical vapor deposition and powder formation using thermal spray with near supercritical and supercritical fluid solutions

A method for chemical vapor deposition using a very fine atomization or vaporization of a reagent containing liquid (T) or liquid-like fluid (T) near its supercritical temperature, where the resulting atomized or vaporized solution (N) is entered into a flame or a plasma torch (170), and a powder is formed or a coating is deposited onto a substrate (190). The combustion flame (170) can be stable from 10 torr to multiple atmospheres, and provides the energetic environment in which the reagent contained within the fluid (T) can be reacted to form the desired powder or coating material on a substrate (190). The plasma torch likewise produces the required energy environment, but, unlike the flame, no oxidizer is needed so materials stable in only very low oxygen partial pressures can be formed. Using either the plasma torch or the combustion flame (170), coatings can be deposited and powders formed in the open atmosphere without the necessity of a reaction chamber, but a chamber may be used for various reasons including process separation from the environment and pressure regulation.
