产品名称：Plasma spray

Such as plasma spraying the basic principle shown in Figure 6,to ignition between an anode and a cathode,yogenerate high-frequency arc.The gas(such as:helium,hydrogen,nitrogen or a mixed gas)flowing between the electrodes is ionized,thereby generating several centimeters long plasma flame.SUch as the temperature of the center of the plasma flame as high as 16000°K.The spraying materal from the gun nozzle to a powder and injected into the plasma flame and melted,and finally to be a compressed gas highspeed jet to from a coating on a substrate. Because of the high temperature of the plasma flame,particularly suitable for spraying a ceramic material such as AI2O3,ZrO2,etc.,can be the material of choice.Widelyused in the aerospace industry.
