Title (EN) SURFACE TREATMENT METAL POWDER FOR LASER SINTERING
(FR) POUDRE MÉTALLIQUE DE TRAITEMENT DE SURFACE POUR FRITTAGE LASER
(JA) レーザー焼結用表面処理金属粉
Abstract:
(EN) A surface treatment metal powder having any of the following characteristics is provided as a metal powder that can be suitably used for metal AM and has excellent laser absorbing characteristics: the brightness L* of the surface is 0-50; the color difference ΔEab of the surface is 40 or more; the color difference ΔL of the surface is -35 or less; the color difference Δa of the surface is 20 or less; and the color difference Δb of the surface is 20 or less (when determined on the basis of the object color of a white plate (brightness L* = 94.14, color coordinate a* = -0.90, color coordinate b* = 0.24)).
(FR) L'invention concerne une poudre métallique de traitement de surface qui possède l'une quelconque des caractéristiques suivantes et qui est fournie sous la forme d'une poudre métallique, qui peut être utilisée de façon appropriée pour une fabrication additive à base de métaux et qui possède d'excellentes caractéristiques d'absorption laser : la luminosité L* de la surface est de 0 à 50 ; la différence de couleur ΔEab de la surface est d'au moins 40 ; la différence de couleur ΔL de la surface est de -35 ou moins ; la différence de couleur Δa de la surface est d'au plus 20 ; la différence de couleur Δb de la surface est d'au plus 20 (lorsqu'elle est déterminée sur la base de la couleur d'objet d'une plaque blanche, avec la luminosité L* = 94,14, et les coordonnées de couleur a* = -0,90, b * = 0,24).
(JA) 以下の何れかの特性を備えた表面処理金属粉によって、金属AMに好適に使用できる、レーザー吸収性に優れた金属粉を提供する:表面の明度L*が0以上50以下である;表面の色差ΔEabが40以上である;表面の色差ΔLが-35以下である;表面の色差Δaが20以下である;表面の色差Δbが20以下である(白色板の物体色(明度L*=94.14、色座標a*=-0.90、色座標b*=0.24)を基準とした場合)。
