arc discharge การใช้

• CVD diamond growth typically occurs under low arc discharges, among others.
• The carbon rod is then put in a DC arc discharge reactor.
• However, it is more expensive than either arc discharge or chemical vapor deposition.
• Combustion or electrical arc discharge is usually used as the source of energy for thermal spraying.
• By 1970, forming machines based on submerged arc discharge, were available from machine tool builders.
• The conference paper described carbon nanotubes as carbon fibers that were produced on carbon anodes during arc discharge.
• If the voltage is increased to the point the cathode glow covers the entire cathode arc discharge begins.
• Each pulse remains a glow up to a critical duration after which it transits to an arc discharge.
• After arc discharging for a period of time, a carbon rod is built up at the cathode.
• The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger borosilicate glass bulb.
• Operation of the rectifier relies on an electrical arc discharge between electrodes in a sealed envelope containing mercury vapor at very low pressure.
• Like carbon nanotubes formed using the electric-arc discharge technique, carbon nanotube fibers are deposited in a haphazard and tangled fashion.
• The gases are ionized into chemically active arc discharge, a welding torch, a laser, an electron beam, or other means.
• The potential forming capabilities of submerged arc discharge processes were recognized as early as the mid-1940s ( Yutkin L . A . ).
• He was among the scientists and engineers who claimed to have confirmed the output of excess electric energy from tuned pulsed plasmas in vacuum arc discharges.
• These are most often used when a load ( such as an arc discharge ) has its terminal voltage decline when current through the load increases.
• A number of methods have been reported to produce carbon nanoscrolls, including arc discharge, high-energy ball milling, and intercalation, among others.
• The electrons will ionize the gas by collisions with the gas in the tube, and an avalanche effect results, causing an arc discharge between cathode and anode.
• As they heat up during operation, however, the internal gas pressure within the arc tube rises and a higher voltage is required to maintain the arc discharge.
• With a small positive bias applied to the grid, electrons pass through the grid, towards the anode, and the process of establishing an arc discharge can commence.
