Electrode Erosion in a High Energy Spark Gap*
The erosion rates for hemispherical electrodes, 2.5 em in diameter, made of graphite, copper-graphite, brass, two types of copper-tungsten, and three types of stainless steel have been examined in a spark gap filled with air or nitrogen at one atmosphere. The electrodes were subjected to 50,000 unipolar pulses (25 )ls, 4-25 kA, 5-30 kV, 0.1-0.6 Coul/shot) at repetition rates ranging from 0.5 to...
متن کاملEffect of electrode erosion on the required ignition voltage of spark plug in CNG spark ignition engine
In this article, the electrode erosion and the gap growth of spark plugs were measured on of a CNG fueled engine after durability tests. Then, the required ignition voltage and the spark quality were investigated by a spark plug test rig. Considering results of measurements, the gap growth increased as the running time increased. Thus, the gap growth of spark plugs with 200 and 280 hours runnin...
متن کاملSpark erosion as a metal-resin bonding system.
PURPOSE Resin to metal bond strength of two commercial and one experimental metal-resin bonding system for crown and bridge veneer composites was evaluated. MATERIALS AND METHODS All specimens were prepared and tested according to ISO 10477 Amendment 1. A high precious alloy (HPA), a Co/Cr-alloy (Co/Cr) and pure titanium (Ti) were wet-ground to a final surface finish of 800 grit and air-dried...
متن کاملAerosol Generation by Spark Discharge*
An aerosol generator producing particles of any desired mobility, equivalent radius, and conducting material has been developed. Particles are formed by electrode atomization in a spark discharge. A high yield of charged particles enables generation of high concentration (> 10’ cmm3) monodisperse aerosols using electrostatic classification. In order to obtain nonagglomerated particles, the aero...
متن کاملAn Experimental Investigation of Spark Plug Temperature in Bi-fuel Engine and Its Effect on Electrode Erosion
Temperature is one of the effective parameters in erosion of spark plug electrodes. In this research, temperature of spark plug was measured in engine's different operation conditions with two types of fuels: compressed natural gas and gasoline. Test results showed that, temperature of center electrode is lower than ground electrode and maximum difference between them is 110ºC that occurs at...
