Abstract
The invention relates to a jet plasma water-cooling spraying gun which comprises a high frequency power supply, an anode sleeve and a cathode. The cathode is arranged in the middle of the anode sleeve, the anode sleeve and the cathode are respectively connected to the positive electrode and the negative electrode of the high frequency power supply, and an outer interlayer water-cooling channel layer is arranged in the anode sleeve. The jet plasma water-cooling spraying gun feeds in gas between the two electrodes, and the gas passes through the electric fields to generate high temperature plasma. Due to the fact that the water-cooling interlayer is arranged in the anode sleeve, the plasma gas at high temperature can be cooled to be plasma fluid. Processing temperature is low, and the negative pressure condition is unnecessary, so that the jet plasma water-cooling spraying gun also can work under an ordinary atmosphere environment, process materials better and enable the material surface modification processing effect of the materials to be better.
