method of formation of gas-powder flow AT plasma application of coatings

摘要

A method of formation of gas-powder flow at plasma application of coating, at which the initial and large part of the basic section of arc is located at input of arc channel, and smaller part of the basic section of arc and its near-electrode section is located in the output section of arc channel, at angle to the initial and basic sections of the arc. Dispersed material is introduced to the zone of transition of the inlet section of the arc channel to the outlet section, coaxially with the direction of discharge of plasma flow.
