Description
【発明の詳細な説明】 のである。[Detailed description of the invention] It is.
特に本発明は予備成形後のサイジング加工に際して潤滑
剤としてポリオキシアルキレン化合物を用いる粉末焼結
物品の製造方法に関するものである。In particular, the present invention relates to a method for producing a powder sintered article using a polyoxyalkylene compound as a lubricant during sizing after preforming.
粉末焼結による加工はその省資源性,省エネルギー性の
ため,従来切llII,鋳造、°鍛造によシ製造されて
いた部品の製造に広く用いられ峻めている。Processing by powder sintering is widely used to manufacture parts that were conventionally manufactured by cutting, casting, and forging because of its resource-saving and energy-saving properties.
粉末焼結に際しては加工精度の向上の丸め。Rounding improves processing accuracy during powder sintering.
一旦予備成形を行った後、サイジング加工をサイジング
剤と称する潤滑油を塗布または含浸して行ない、次いで
最終的に焼結を行う方法が取られている。After preforming, a sizing process is performed by applying or impregnating a lubricating oil called a sizing agent, and then finally sintering is performed.
この際の潤滑油としては通常鉱油や、動植物油等が用い
られているが、焼結時に潤滑油が炭化し,焼結物品の性
能や美観に悪影・響を与えてしまう。Mineral oil, animal and vegetable oils, etc. are usually used as the lubricating oil in this case, but the lubricating oil is carbonized during sintering, which adversely affects the performance and aesthetics of the sintered article.
これをさけるために焼結前に溶剤で洗浄したシ,焼結後
酸化性写囲気中で熱処理する方法もあるが、工程が増加
し、好ましいものではない。To avoid this, there is a method in which the material is washed with a solvent before sintering and then heat treated in an oxidizing atmosphere after sintering, but this method increases the number of steps and is not preferable.
本発明の目的は粉末成形物品の性能等に悪影響を及ぼさ
