Abstract
(EN)
A sintered bearing (1) contains 3-12 weight percent of aluminum and 0.05-0.5 weight percent of phosphorus, has copper as the balance of the main components, and contains unavoidable impurities. The sintered bearing (1) is characterized by having a structure in which an aluminum-copper alloy is sintered using a sintering agent added to a starting material powder, and in that pores (db, do) in a front layer section of the sintered bearing (1) are formed smaller than internal pores (di).
(FR)
Un palier fritté (1) contient 3 à 12% en poids d'aluminium et de 0,05 à 0,5 pour cent en poids de phosphore, contient du cuivre en tant que balance des composants principaux, et contient des impuretés inévitables. Le palier fritté (1) est caractérisé par le fait qu'il possède une structure dans laquelle un alliage d'aluminium-cuivre est fritté à l'aide d'un agent de frittage ajouté à une poudre de matériau de départ et en ce que des pores (db, do) dans une section de couche avant de ce palier fritté (1) sont formés plus petits que les pores internes (di).
(JA)
 3~12質量%のアルミニウムおよび0.05~0.5質量%の燐を含有し、残部の主成分を銅とし、不可避不純物を含んだ焼結軸受1であって、この焼結軸受1が、原料粉末に添加した焼結助剤によりアルミニウム-銅合金が焼結された組織を有し、かつ焼結軸受1の表層部の気孔db、doを内部の気孔diより小さくしたことを特徴とする。
