Title (EN) METAL POWDER FOR MOLDING METAL LAMINATE AND MOLDED OBJECT MANUFACTURED USING SAID METAL POWDER
(FR) POUDRE MÉTALLIQUE POUR MOULAGE DE STRATIFIÉ MÉTALLIQUE ET OBJET MOULÉ FABRIQUÉ À L'AIDE DE LADITE POUDRE MÉTALLIQUE
(JA) 金属積層造形用金属粉及び該金属粉を用いて作製した造形物
Abstract:
(EN) This metal powder is characterized in that: a coating film, which is composed of at least one among Gd, Ho, Lu, Mo, Nb, Os, Re, Ru, Tb, Tc, Th, Tm, U, V, W, Y, Zr, Cr, Rh, Hf, La, Ce, Pr, Nd, Pm, and Sm, is formed on the surface of copper or copper alloy powder; and the film thickness of said coating film is 5-500 nm. The present invention addresses the problem of providing: metal powder for molding a metal laminate by a laser method, in which the metal powder can be efficiently melted by laser while retaining the high conductivity of copper or a copper alloy; and a molded object manufactured using said metal powder.
(FR) L'invention concerne une poudre métallique caractérisée : en ce qu'un film de revêtement, qui est composé d'au moins un élément parmi Gd, Ho, Lu, Mo, Nb, Os, Re, Ru, Tb, Tc, Th, Tm, U, V, W, Y, Zr, Cr, Rh, Hf, La, Ce, Pr, Nd, Pm et Sm, est formé sur la surface de poudre de cuivre ou d'alliage de cuivre ; et en ce que l'épaisseur de film dudit film de revêtement est de 5 à 500 nm. La présente invention aborde le problème consistant à fournir : une poudre métallique pour mouler un stratifié métallique par un procédé laser, dans lequel la poudre métallique peut être fondue de manière efficace par laser tout en conservant la conductivité élevée du cuivre ou d'un alliage de cuivre ; et un objet moulé fabriqué à l'aide de ladite poudre métallique.
(JA) 銅又は銅合金粉の表面に、Gd、Ho、Lu、Mo、Nb、Os、Re、Ru、Tb、Tc、Th、Tm、U、V、W、Y、Zr、Cr、Rh、Hf、La、Ce、Pr、Nd、Pm、Smのいずれか一種以上からなる皮膜が形成され、前記皮膜の膜厚が5nm以上500nm以下であることを特徴とする金属粉。本発明は、レーザー方式による金属積層造形用金属粉であって、銅又は銅合金の高い導電性を維持しつつ、効率良くレーザーによる溶融ができる、金属粉及び該金属粉を用いて作製した造形物を提供することを課題とする。
