APPLICATION METHOD FOR COLD FIELD PLASMA DISCHARGE ASSISTED HIGH ENERGY BALL MILLED POWDER AND DEVICE

Document Type and Number:

WIPO Patent Application WO/2016/101187

Kind Code:

A1

Abstract:

An application method for cold field plasma discharge assisted high energy ball milled powder and a plasma assisted high energy ball milling device using the method for cold field plasma high energy ball milled powder. Plasmas are generated by using dielectric barrier discharge, and a dielectric barrier discharge electrode bar (4) is introduced into a high-speed vibrating ball milling tank (3). On one hand, a solid insulation medium on the outer layer of the electrode bar can simultaneously bear high-voltage discharge and mechanical shock failure of the grinding ball, and on the other hand, the high-speed vibrating ball milling device can uniformly process the powder. Based on the ordinary ball milling technology, the discharge space pressure is set to a non-thermal equilibrium discharge state with a pressure of about 102 to 106 Pa, discharge plasmas are introduced to input another kind of effective energy to the processed powder, so as to accelerate refining of the powder to be processed and promoting the alloying process under the combined action of the mechanical stress effect and the heat effect of the external electric field, thereby greatly improving the processing efficiency and the effect of the ball mill.
