method of formation of gas-powder flow at plasma spraying of ferromagnetic material

摘要

A method of formation of gas-powder flow at plasma spraying of ferromagnetic material includes radial introduction of dispersed material in the plasma jet of sprayer of indirect effect with residual peripheral component of velocity of gas flow. To the end segment of arc stream and initial section of plasma jet external transverse scanning magnetic field is applied with direction of displacement of the maximum of induction, which is opposite to the direction of preliminary twisting of gas.
