Modification of W and Re Powders by Plasma Technique
Selected measurement results of plasma spheroidization of tungsten and rhenium powders are presented in the paper. The powders can be applied for production of sinters intended for armor-piercing penetrating cores (kinetic energy penetrators) or high-current electric contacts. Spheroidization of these powders was carried out on the stand for plasma spraying in a chamber filled with neutral gas. Changes of shape and size of powder particles after spheroidization are demonstrated. Measurement results of internal stresses in powder particles are presented.
