Kurzbeschreibung (Abstract)
A common method for producing metal powders used for additive manufacturing is based on the atomization of a stream of molten metal by means of a high-pressure gas flow. In the present experimental study, the influence of the liquid mass flow rate on the atomization result has been investigated for a close-coupled atomizer operated with water and air as a substitute for molten metal and argon gas. The phase Doppler measurement technique has been employed to measure local particle size and velocity distributions within the spray. The results indicate that the liquid mass flow rate is a sensitive parameter in determining the mean particle size as well as the width of the particle size distribution. Its influence appears to be strongest in the center of the spray. Here, a decrease in the liquid mass flow rate has been found to lead to a significant decrease in the arithmetic mean particle diameter and a considerably narrower particle diameter distribution.
