Composition Changes according to the Manufacturing Method of Dental Alloy Powder for Application of Selective Laser Melting System

摘要

Nozzle Spouting and ball milling were tested to analyze the way to process Ni-Cr alloy into powder. As the results, Ni and Cr of powders processed by nozzle spouting were reduced and the powder analyzed by a laser test has a regular round shape. To apply SLM on Ni-Cr alloy powders, it should be designed after considering substance changes of composition after processing it into powder by nozzle spouting. The way to process subjects into round shapes is required for using ball milling. Through this kinds of additional research, Ni-Cr alloy powder will be able to be used as process materials of SLM.
