Abstract
Description
本発明の目的は、大きな取り出し力及び焼結された部品の表面汚れの問題を低減するか消失させる潤滑剤及び/又は結合剤を含む新規な粉末金属組成物を提供することである。
本発明による粉末金属組成物中の潤滑剤及び/又は結合剤は、一般式:
R1−NH−CO−R2
(式中、R1−及びR2−基は、同じか又は異なり、直鎖又は分岐鎖、飽和又は不飽和脂肪族炭化水素基である。)
により定義することができる少なくとも一種の第二級アミドである。
この例は、鉄系粉末混合物中に粉末として添加される種々の第二級アミド及び第二級と第一級アミドの種々の組合せの潤滑性を立証するものである。
基礎粉末ASC 100.29を、2重量%の銅(−100μm)、0.8重量%の黒鉛、及び0.8重量%の潤滑剤〔a)EBS又はb)オレイルパルミトアミド〕と2分間レーディゲ混合機で混合した。潤滑剤は150μmより小さい粒径を持っていた。部品を焼結した後の汚れの形成を測定するため、直径64mm及び高さ32mmの円柱部品を周囲温度で7.1g/cm3の素地密度まで圧縮した。一つの円柱の重量は700gであった。それら部品を90/10のN2/H2を含有する雰囲気中で1120℃で15分間焼結した。それら部品の写真を図1a)エチレンビスステアルアミド(EBS)及び1b)オレイルパルミトアミドに示すが、図1a)は、汚れのない本発明による粉末組成物(1b)から製造された部品とは対照的に、汚れの形成を示している。
この例は、第二級及び第一級アミドの種々の組合せの潤滑性を立証するものであり、それらは一緒に溶融し、冷却し、粉砕した後、鉄系粉末混合物と混合された。
この例は、粉末金属組成物中のアミドの種々の組合せの潤滑性及び結合性を立証するものである。
粗い電磁軟鉄系粉末で、粒子が無機絶縁体で取り囲まれているものを、表9に従い、第二級アミド潤滑剤と混合した。基準潤滑剤として既知の物質であるステアリン酸亜鉛及びEBSを用いた。用いた鉄系粉末の粒径分布を表10に開示する。
