Gas barrier film.

Relevancy:  

Gas barrier film having a thermoplastic polymer film, and an inorganic thin film provided on at least one surface of the thermoplastic polymer film, which gas barrier film is formed by applying, to the inorganic thin film, a solution which contains at least one ion species selected from the group consisting of alkali metal ions, alkaline earth metal ions, and ammonium ions and originating from a low-molecular-weight electrolyte having a molecular weight of 1,000 or less and which has a total ion concentration of the ion species of 1x10<-5 >mol/L or more and less than 10 mol/L and a solution concentration less than a saturation concentration.

Gas barrier laminated material

Relevancy:  

Gas barrier laminated material comprising polymeric sheet or film, 50-3,000 thick layer of inorg. compound, and 0.01-100µm thick protective layer formed by coating inorg. compound with water based coating incl. metal alkoxide or hydrolyzate or tin chloride, then heating and drying.

Gas barrier multilayer film and method for producing same.

Relevancy:  

Transparent laminated film has base material & vapour-deposited inorganic oxide, primer coated, then heated.

Gas Barrier Performances of Silica Films Deposited on Poly (Ethylene Terephthalate) Substrates by Plasma-Enhanced CVD

Relevancy:  

Transparent gas barrier silica films were synthesized on poly(ethylene terephthalate) substrates by a low-temperature plasma-enhanced chemical vapor deposition method using an organosilane/oxygen mixture. The gas barrier performances of the films were significantly affected by their structures and chemical compositions. Structural defects, such as grain boundaries, pinholes and cracks, degraded the gas barrier performance, as well as chemical-compositional defects, such as loosely packed siloxane-networks and imperfect siloxane-networks, due to the termination of networks with impurities. An excellent gas barrier performance was attained with a silica film consisting of densely-packed and fully cross-linked siloxane-networks.

Gas barrier properties and periodically fractured surface of thin DLC films coated on flexible polymer substrates.

Relevancy:  

Gas Barrier Properties of Carbon Films Synthesized by Atmospheric Pressure Glow Plasma.

Relevancy:  

Gas barrier transparent resin substrate, method for manufacture thereof, and flexible display element using gas barrier transparent resin substrate.

Relevancy:  

Uses tin oxide amorphous transparent coating film with an added element, incl. forming duplex layer where silicon oxide or oxynitride is formed over the tin oxide layer. Because the tin oxide is electrically conductive, a flexible electrochromic display can be created.

Gas bearing spindles.

Relevancy:  

For use in, e.g ion implantation equipment, surface is coated with chromium or other hard material.

Gas Bubble Behavior during Water Electrolysis.

Relevancy:  

The various regions of the gas prodn. rate curve were investigated and related to the similar behavior of the boiling curve. The effects of temp., electrolyte concn. and electrode material on the max value of the c.d. were studied for both electrodes. The effects of electrolyte concn. is very essential. In agreement with theor. predictions, gas bubble growth during electrolysis is mass transport diffusion controlled, i.e. the bubble radius is proportional to the square root of time. The bubble behavior was studied for different geometries and various types of electrodes.

Gas carbonitriding for precision gear

Relevancy:  

Surfaces of 20CrMnTi steel sun and planet gears were hardened by gas carbonitriding at 870°C and 400 Pa for 5 hours. The depth and hardness of the carbonitrided layers was measured. The gears were tested in production applications.

Gas carburizing

Relevancy:  

Gas carburizing process comprises treatment with hydrocarbon gas and oxidative gas in heat treating furnace. When pressure is negative, carbon dioxide is fed into furnace for dissolving negative pressure.

Gas carburizing

Relevancy:  

Gas carburizing of metallic components at high temp. and under carbon monoxide-hydrogen atmos. by reaction of hydrocarbon-containing carbon dioxide medium, esp. ethanol formed from CO2.

Gas carburizing apparatus

Relevancy:  

.

Gas carburizing highly alloyed steel

Relevancy:  

Applying surface coating to promote gas carburizing of non-planar specimen of highly alloyed steel, by coating specimen with layer of iron; and carburizing in conventional gas carburizing equipment.

Gas carburizing process

Relevancy:  

Material is pre-heated to 750-960°C and heat treated in carburizing atmos. directly supplied with hydrocarbon and oxidizing gases in which it is heated to 1000-1100°C; cooled to <600°C; reheated to 750-850°C; and hardened by quenching in oil, pref. by means of laminar flow quenching.
