IMPROVED METHODOLOGY FOR MEASURING THE EMISSIVITY OF METAL POWDERS

Анотація


A specially designed chamber is proposed to accurately measure the emissivity coefficient of metal powders over a wide temperature range using an infrared (IR) camera. This measurement setup significantly reduces the oxidation of metal powders during heating to high temperatures. As a result, it enables precise determination of the actual emissivity values, which is crucial for accurate IR camera calibration when studying sintering or melting processes in additive manufacturing.
