Abstract

A microwave-driven plasma spraying apparatus can be utilized for uniform high-powered spraying. The plasma sprayer is constructed without a dielectric discharge tube, so very high microwave powers can be utilized. Moreover, the plasma sprayer is relatively free of contamination caused by deposits of heat-fusible material.
