摘要:
The present invention is a film-forming apparatus including: a mist-generating member to atomize a raw material solution into a mist; a carrier gas-supplying member to supply a carrier gas for carrying the mist generated in the mist-generating member; and a film-forming member to thermally treat the mist carried with the carrier gas to form a film, wherein the film-forming member includes: a film-forming chamber; a substrate-placing member provided inside the film-forming chamber; a nozzle to supply the mist toward the inside of the film-forming chamber; and a gas-discharging member to discharge an exhaust gas from the inside to an outside of the film-forming chamber, and a difference in a height position between an inner face of a ceiling of the film-forming chamber and a substrate-placing face of the substrate-placing member is 0.15 cm or longer and 6.05 cm or shorter. This provides a film-forming apparatus that can form a film with excellent in-plane uniformity of film thickness by mist CVD.

Liquefied gas (34) from a tank (3) passes via the dosing unit (5) through an evaporator (2) converting it to a gas. This is fed to a reactor (20). An energy source (21) produces a reactive zone (32) there. The reaction products are used to coat the workpiece (30). The mass flowrate of the gas in the reactor is adjusted by a unit controlling the flow of the liquid gas (40) into the evaporator. For plasma-assisted vapor phase deposition of layers onto workpieces, the reactor is evacuated by a pump (26). The gas is supplied to the evacuated region. Plasma is excited there, using an electromagnetic field. The products coat the workpiece. The volumetric flow set by dosing is preferably about 20 nl/min - 10 mu l/min. Dosing precision is preferably 0.3 mu l/min or better. The process gas component is mixed with a second gas in the evaporator (2). A mass flowrate sensor measures the flow of liquid gases to the evaporator. The evaporation rate exceeds the introduction rate into the evaporator. The pressure in the reactor is controlled using a throttle valve (24) in the vacuum line to the pump. The first process gas component is a metastable substance. It has no lasting stability at 130[deg] C, or at the temperature in the evaporator. A mixture of two components at least, is dosed in liquid form. A first process gas component is vaporized and supplied to the reactor. At a temperature of 130[deg] C, this has a vapor pressure preferably less than 50mbar. A polyether is a component of the first process gas. This is preferably a non-cyclic polyether, especially a mono-, di-, tri-, tetra-, penta-, or hexaethylene glycol-dimethyl ether, preferably tetraethylene glycol-dimethyl ether. It is vaporized as the first process gas component. A polyethylene glycol-containing- or polyethylene glycol-like coating is deposited on the workpiece. The pulse energy used, does not exceed 3 joules. An independent claim IS INCLUDED FOR corresponding apparatus.

摘要:
A chemical vapor deposition (CVD) system and method for applying an aluminide coating (34) constituted by two or more extrinsic metal components on a jet engine component (26). The aluminide coating (34) is capable of forming a protective complex oxide upon subsequent heating in an oxidizing environment. At least one of the extrinsic metals in the aluminide coating (34) is provided as a distinct vapor phase reactant (37) from a receptacle (36) coupled by a closed communication path (40) with the reaction chamber (12) of the CVD system and free of a carrier gas. The aluminide coating (34) is formed by the chemical combination of the vapor phase reactant (37) with another vapor phase reactant (35) either created in situ in the reaction chamber (12) or supplied by a carrier gas to the reaction chamber (12) from a precursor source (60).
