Abstract
(EN)
Provided is a mixed powder for powder metallurgy that includes a readily available compound as a lubricant, that need not include a metal soap which causes staining, that has exceptional extractability and compressibility, and that furthermore can exhibit exceptional fluidity without any reduction in the extractability and compressibility even when carbon black is included. A mixed powder for powder metallurgy containing (a) an iron-based powder and (b) a lubricant, wherein the (b) lubricant is an ester of a disaccharide and a fatty acid represented by R-COOH, and R is a C11 or higher alkyl group or a C11 or higher alkenyl group.
(FR)
L'invention concerne une poudre mélangée pour métallurgie des poudres qui comprend un composé facilement disponible en tant que lubrifiant, qui n'a pas besoin d'inclure un savon métallique qui provoque une coloration, qui a une aptitude à l'extraction et une compressibilité exceptionnelles, et qui peut en outre présenter une fluidité exceptionnelle sans aucune réduction de l'aptitude à l'extraction et de la compressibilité même lorsque du noir de carbone est inclus. La présente invention concerne une poudre mélangée pour métallurgie des poudres contenant (a) une poudre à base de fer et (b) un lubrifiant, le lubrifiant (b) étant un ester d'un disaccharide et d'un acide gras représenté Par R-COOH, et R étant un groupe alkyle en C11 ou plus ou un groupe alcényle en C11 ou plus.
(JA)
容易に入手可能な化合物を潤滑剤として含み、汚れの原因となる金属石鹸を含む必要がなく、抜出し性および圧縮性に優れ、さらにカーボンブラックを含む場合にも抜出し性および圧縮性を低下させることなく優れた流動性を発揮することができる、粉末冶金用混合粉を提供する。 (a)鉄基粉末および(b)潤滑剤を含有する粉末冶金用混合粉であって、前記(b)潤滑剤が、二糖類と、R-COOHで表される脂肪酸とのエステルであり、前記Rが炭素数11以上のアルキル基または炭素数11以上のアルケニル基である、粉末冶金用混合粉。
