摘要:
An improved process for treating an electrically conductive surface of a workpiece by cleaning or coating the surface is provided, comprising the steps of deploying the electrically conducting surface of the workpiece to form a cathode in an electrolytic cell; establishing a DC voltage between the cathode and an anode; forming a working gap between the anode and the cathode, and establishing a seal around the working gap to form a sealed treatment zone; delivering into the working gap an electrically conductive medium selected from the group consisting of: (A) an aqueous electrolyte from which a foam is created; (B) a foam; and a mixture of components (A) and (B), so that electrically conductive medium consisting of a foam comprising a gas/vapor phase and a liquid phase fills the working gap, wherein said electrically conductive medium enters the electrolytic cell through tubes having discharge ends oriented at approximately ten degrees from parallel to the workpiece, and wherein turbulence is created within the electrolytic cell; adjusting the operating parameters so that an electro-plasma discharge is created between the cathode and positive ions in the electrically conductive medium which are concentrated near the electrically conducting surface of the workpiece, thereby causing micro-zonal melting of the surface; and removing foam from the working gap.
摘要:
A method of improving the material properties of a composite by electrodepositing various polymers, organic compounds or inorganic compounds onto each individual carbon (graphite) fiber strand, whether individual fiber or as a fabric to form an homogeneous chemically-bonded composite as opposed to the formation of a heterogeneous, non-chemically bonded composite. Thus, electrodeposition forms a unique discrete interface at the molecular layer (nanolayer) between the reinforcement (fiber) and the matrix (resin) over as opposed to any previous resin infusion process.
摘要:
A first process for the production of a thin nitrogenous layer on a semiconductor surface by contacting at least a part of the surface with a nitrogenous liquid, by applying an electrical voltage between the surface, the liquid and an electrode according to a given voltage-time curve until a layer thickness of less than 5 nm is formed, and then separating the surface from the liquid. A second process for the production of a thin nitrogenous layer on a metal surface or on a metal layer located on a substrate by contacting at least a part of the surface or the metal layer with a nitrogenous liquid, by applying an electrical voltage between the surface or metal layer, the liquid and an electrode according to a given voltage-time curve until a layer thickness of less than 50 nm is formed, and then separating the surface or the metal layer from the liquid. A third process for detaching an oxygen-containing and/or nitrogenous layer on a semiconductor or a metal surface.
