The methods of plasma jet noise suppression for plasma metallizing are described.
In this study the new muffler of reactance type which have the functions of noise suppression and plasma jet atmosphere control has been developed.
Examining the effects of muffler under the various conditions, it has indicated that the value of noise attenuation is obtained from 12 to 21 dB, and the gas concentration and temperature of plasma jet are kept at the good conditions for plasma metallizing.
