摘要: Deposition of coatings using an atmospheric pressure plasma jet. The use of a nonthermal source which is capable of operation at 760 torr is demonstrated. As an example of the application of the present invention, a helium/oxygen gas mixture is introduced into the annular region between two coaxial electrodes driven by a 13.56 MHz radio frequency (rf) source at between 40 and 500 W to produce a stable plasma jet. Silicon dioxide films are deposited by introducing tetraethoxysilane (TEOS) into the effluent stream. A deposition rate of 3020±250 Å/min. is achieved with an rf power of 400 W, 0.2 torr of TEOS, 11.1 torr of oxygen, 748.7 torr of helium, and a total gas flow rate of 41 L/min. The deposition rate depends on the oxygen partial pressure, the TEOS partial pressure, and the rf power to the 0.28, 0.47, and 1.41 powers, respectively. However, increasing the temperature decreases the deposition rate. The observed dielectric constants of the films decrease from 5.0±0.2 to 3.81±0.03 as the deposition temperature increases from 115 to 350° C. Infrared spectra of the deposited films at 350° C. show no carbon or hydroxyl ion contamination, indicating excellent material purity.

摘要: An apparatus for removing selected metal ions from a plasma includes a plasma chamber and at least one silica substrate mounted inside the chamber. More specifically, the substrate is exposed in the chamber so that when metal ions from the plasma contact the substrate they diffuse into the substrate to create a liquified layer. A receptacle is also provided to receive the liquid from the layer as it flows from the substrate.

摘要: In the process for coating the elastomeric rubber wiper a vaporous coating material is generated and activated by a plasma and/or laser; a protective coating is formed on a rubber wiper surface by exposing it to the vaporous coating material by CVD and/or PVD methods and process parameters for the coating process are controlled so that the protective coating includes at least three coating layers and has a total thickness of from 200 nm to 2 &mgr;m. The coating layers include at least one thicker softer elastic coating layer with elastomeric properties similar to those of the rubber wiper and other thinner harder coating layers having wear-resistant properties. The other thinner harder coating layers have respective hardness increasing from an inner most one to an outermost one of the other thinner harder coating layers.
