Nitric Oxide Generator Based on Pulsed Arc Discharge
Nitric oxide (NO) is increasingly being used in medical applications. Currently, a gas cylinder of N2 mixed with a high concentration of NO is used in the NO inhalation system. However, this arrangement is potentially risky due to the possibility of accidental leak of NO from the cylinder. The presence of NO in air leads to the formation of nitric dioxide (NO2), which is toxic to the lungs. The...
متن کاملMacroparticle Charging in a Pulsed Vacuum Arc Thruster Discharge
A pulsed vacuum arc discharge emits a plasma as well as macroparticles in the form of micron-sized molten droplets of cathode material. Due to their trajectory and size, these macroparticles often pose a contamination threat for both spacecraft-based thrusters, and thin film deposition systems. The charge of these macroparticles was experimentally measured, and compared to a model based on ther...
متن کاملStudy of Multilayer Coatings of Ti/TiN/TiC Produced by Pulsed Arc Discharge
This work presents a study of multilayered Ti/TiN/TiC thin films obtained using a PAPVD (Plasma Assisted Physical Vapor Deposition) system by pulsed-arc discharge. For this purpose, a titanium target and a stainless steel substrate were used, placed on the cathode and on the anode, respectively, inside a vacuum chamber. To grow these films, different gases and concentrations were required. Ti i...
متن کاملBench-Scale Disinfection of Bacteria and Viruses with Pulsed Arc Electrohydraulic Discharge
Pulsed arc electrohydraulic discharge (PAED) offers concurrent treatment of chemical and microbial target compounds in water by several mechanisms. Here, Escherichia coli, Bacillus subtilis spore, and MS2 bacteriophage inactivation by PAED were investigated using two bench-scale reactors (0.7 and 3 L). A plasma channel was created between a pair of iron electrodes set 0.5 mm apart in these reac...
متن کاملArc Shape Characteristics with Ultra-High-Frequency Pulsed Arc Welding
Arc plasma possesses a constriction phenomenon with a pulsed current. The constriction is created by the Lorentz force, the radial electromagnetic force during arc welding, which determines the energy distribution of the arc plasma. Welding experiments were carried out with ultra-high-frequency pulsed arc welding (UHFP-AW). Ultra-high-speed camera observations were produced for arc surveillance...
