摘要： The invention relates to a method of forming a silicon diffusion and/or overlay coating on the surface of a metallic substrate comprising the steps of introducing the sample into a cold wall Low Pressure Chemical Vapor Deposition (LPCVD) enclosure, evacuating the enclosure up to a pressure P.sub.1 which is lower than 0.5 Torr, maintaining said pressure P.sub.1 while heating up said sample to a temperature which is comprised between about room temperature and about 300.degree. C., bringing under same pressure P1 the sample to the CVD temperature comprised between about 50.degree. C. and 1000.degree. C., introducing a gas or gas mixture comprising at least one silicon hydride gas, maintaining the pressure inside the enclosure between about 0.1 and about 100 Torr, maintaining the introduction of said gas or gas mixture in the enclosure for deposition and/or diffusion of silicon on and/or through the surface of said metallic sample to obtain the desired thickness of the silicon diffusion and/or overlay coating, cooling down the sample to about room temperature and withdrawing said sample from said LPCVD enclosure. The substrate is preferably polished to obtain a mirror finish and then cleaned, either mechanically or chemically, with a solvent, or both.

摘要： A method of detecting a malfunction or failure of a pressure regulator in a corrosive or reactive gas distribution system while in use involves continuously measuring or monitoring the output pressure of the pressure regulator, both in the presence and the absence of gas flow. The onset of a malfunction of the pressure regulator can be predicted when the differential output pressure between flowing and non-flowing gas fluctuates highly and increases gradually. Failure of the pressure regulator or of the total system is detected when the differential output pressure in the presence and absence of flowing gas exceeds some experimentally determined value.

摘要： A deposition method is provided to enable fine particles having a relatively large particle diameter, for example, a diameter larger than 0.5 μm, to be stably deposited on a substrate. The fine particles with insulating surface are placed in an airtight container, and a carrier gas is introduced into the container, triboelectrically charging the fine particles and generating an aerosol of the fine particles. The fine particles are charged by friction with the inner surface of a transfer tubing connected to the container, and the aerosol is conveyed via such tubing to a deposition chamber that is maintained at a pressure lower than that in the airtight container. The charged fine particles are deposited on a substrate placed in the deposition chamber.
