Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to an anode high-pressure low-temperature nitriding device. Background technique [0002] There are many methods of plasma surface metallurgy in the prior art, among which glow ion nitriding is carried out by using the principle of glow discharge. When the gas passes through the corona discharge area, if the external circuit resistance is reduced or the entire circuit voltage is increased, the process continues. Increase the discharge power, the discharge current will continue to rise, and at the same time, the glow will gradually expand to the entire discharge space between the two electrodes, and the light will become brighter and brighter. When the electron energy increases, that is, the operating parameters of the electric field are enhanced, the corona can be made Discharge transitions to glow discharge. This method has disadvantages such as poor ion diffraction...
