摘要： The present invention describes a chemically-assisted machining process that converts conventional lubricant chemistries to produce reactive oxygenated species that accelerate the formation of friction-reducing boundary layer lubrication during cutting operations—termed “Ozonolytic Machining”. The new type of cooling-lubricant chemistry is based on chemical reactions between unsaturated bio-based oils and alcohols, and other types of machining lubricants, containing carbon-carbon double or triple bonds, with ozone gas to form variously reacted or polymerized ozonides—termed “super-oxygenated fluids, oils or alcohols, aldehydes or ketones,” “sulfurized ozonides” and “super-oxygenated gels.”

摘要： An electrostatic spray application apparatus and method for producing an electrostatically charged and homogeneous CO2 composite spray mixture containing an additive and simultaneously projecting at a substrate surface. The spray mixture is formed in the space between CO2 and additive mixing nozzles and a substrate surface. The spray mixture is a composite fluid having a variably-controlled aerial and radial spray density comprising pressure- and temperature-regulated propellant gas (compressed air), CO2 particles, and additive particles. There are two or more circumferential and high velocity air streams containing passively charged CO2 particles which are positioned axis-symmetrically and coaxially about an inner and lower velocity injection air stream containing one or more additives to form a spray cluster. The axis-symmetrical CO2 particle-air streams are passively tribocharged during formation, and the spray clustering arrangement creates a significant electrostatic field and Coanda air mass flow between and surrounding the coaxial flow streams.

摘要： A method of forming a machining spray for treating a surface of a substrate during a machining process includes providing a first component containing solid carbon dioxide particles. A second provided component is derived from an inert gas having a temperature range from 305 K to about 477 K prior to being mixed with the solid carbon dioxide particles. The first component and the second component are combined to form the cryogenic fluid composition prior to contacting the substrate. An optional additive may be mixed with the solid carbon dioxide particles or the inert gas. The cryogenic fluid composition exhibits synergistically enhanced physicochemical properties of each component not observed prior to the combination thereof, wherein the fluid imparts enhanced cooling, heating or lubrication effects.

The constant pressure gas may include carbon dioxide, nitrogen, air or mixtures thereof. The dense fluid preferably includes liquid carbon dioxide at or above its triple point. The liquid carbon dioxide and isobaric gas are independently fed to the rotary union. When mixed, a pressurized flowing carbon dioxide machining fluid composition is formed exhibiting a temperature between about 20° F. and 70° F. at pressures between 75 psi and 1,000 psi.

摘要： The present invention is a method, process and apparatus for selective cleaning, drying, and modifying substrate surfaces and depositing thin films thereon using a dense phase gas solvent and admixtures within a first created supercritical fluid anti-solvent. Dense fluids are used in combination with sub-atmospheric, atmospheric and super-atmospheric plasma adjuncts (cold and thermal plasmas) to enhance substrate surface cleaning, modification, precision drying and deposition processes herein. Moreover, conventional wet cleaning agents such as hydrofluoric acid and ammonium fluoride may be used with the present invention to perform substrate pre-treatments prior to precision drying and cleaning treatments described herein. Finally, dense fluid such as solid phase carbon dioxide and argon may be used as a follow-on treatment or in combination with plasmas to further treat a substrate surface.

摘要： A composition for removing organic contaminants, such a flux residues, from a solid substrate comprises: (a) hydrogen peroxide in the amount of about 3 to 5 percent by weight of the composition; (b) an alkaline compound in sufficient amount to provide a pH of at least 10.5 in the composition; (c) about 0.1 to 0.3 percent by weight of a chosen wetting agent which is unreactive with the hydrogen peroxide and the alkaline compound; and (d) purified water as the balance of the composition. Optionally, the composition may further comprise about 0.5 to 2.0 percent by weight of a chosen metal protective agent.The solid substrate having organic contaminants thereon is exposed to the above noted composition whereby the organic contaminants are removed from the substrate and are converted into non toxic and non-hazardous products. Thus, negative environmental impact is avoided by the present process. In an alternative embodiment, the organic contaminant removal is further enhanced by exposing the composition and the organic contaminants on the substrate to ultraviolet radiation.

摘要： An environmentally safe process for pre-cleaning, sterilizing, preserving, and enhancing performance characteristics of materials used in critical environments with stringent end-product cleanliness and sterilization requirements in a single process using high energy dense fluids. One or more dense fluids are mixed with one or more chemical agents and are simultaneously subjected to a non-uniform electrostatic field and high powered acoustic radiation to remove, in a process called acoustic-electroextraction, deeply recessed contaminants from internal and external surfaces of intricately arranged or formulated materials such as biomaterials, surgical tools, or dental implants. Subsequently, the cleaned materials are than subjected to a high energy dense fluid oxidizing environment to provide for deep material penetration and sterilization and removal of biological contaminants. Finally, the cleaned and sterilized materials may be implanted with chemical agents using an acoustic deposition process to provide for long term preservation. In an alternative embodiment of the present invention, chemical agents may be implanted in materials to provide new and improved material properties such as increased electrical insulation. Finally, the entire process may be performed on materials which are prepackaged in semi-permeable membranes, preventing recontamination of the clean, sterile, or implanted materials.
