Title:
POWDER FOR METAL ADDITIVE MANUFACTURING AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2018/122934
Kind Code:
A1
Abstract:
The present invention relates to a powder for metal additive manufacturing with which, by processing the metal powder so as to lower the pre-sintering temperature, additive manufacturing time can be reduced and unnecessary powder can be easily eliminated after additive manufacturing. This powder for metal additive manufacturing has a conductive material coated onto the surface of metal powder. When the metal powder is a nickel alloy powder that includes nickel as the main component and chromium and iron as the main secondary components, nickel is coated as a conductive material by plating or the like. Moreover, the particle size range for the metal powder is 10 – 200 µm, preferably 25 – 150 µm, and more preferably 45 – 105 µm. In addition, the range for the thickness of the conductive material is preferably 0.1 – 1 µm, and preferably 0.3 µm or greater.
