摘要： PURPOSE:To improve the seizure resistance and wear resistance of the bearing alloy by adding a specified amt. of Sr to an Si-contg. Al-Sn-Pb series alloy having specified compsn. and regulating the shape of Si to a spheroidal one. CONSTITUTION:The bearing alloy is constituted of, by weight, 3 to 35% Sn, 0.1 to 11% Si, 0.1 to 10% Pb, 0.1 to 2% of one or more kinds among Cu, Mg and Zn, 0.1 to 1% of one or more kinds among Cr, Mn, Fe, Ni, Co, Mo, Sb, V and Zr, 0.01 to 0.3% Sr and the balance Al. Furthermore, in the Al matrix 1, Si grains 2 having a spheroidal or elliptical shape or a roundish shape in the tip are dispersed and precipitated. By the grains 2, the ideal of the point contact can nearly be obtd. to moreover increase the lubricity and wear resistance. Moreover, even if high-speed and rapid high loads are applied, the alloy does not flaw the mating shaft and the matrix 1 has no notch effect therein as well as has stabilized strength and excellent wear resistance. Furthermore, Sn-Pb alloys 3 are present more adjacently to the grains 2, by which the lubricity can drastically be improved.

摘要： PURPOSE:To obtain atomized Al alloy powder contg. graphite and suitable for use in the manufacture of a sliding material by uniformly dispersing graphite in the rapidly cooled structure of an Al alloy contg. solubilized Cu. CONSTITUTION:This atomized Al alloy powder contg. graphite contains graphite dispersed uniformly and finely in the rapidly cooled structure of the Al alloy contg. solubilized Cu. An Al alloy or powder of the alloy is melted, graphite coated with Cu is added to the melt, and a cooling medium is jetted on a flow of the melt to obtain said Al alloy powder by atomization. This Al alloy powder 9 contains graphite dispersed uniformly and finely in the rapidly cooled structure 3. Graphite 1 is uniformly mixed with the molten Al alloy by the action of Cu coating the surface of the graphite, and it disperses uniformly and finely in the matrix of the Al alloy. When the Al alloy powder is sintered to manufacture a sliding material, the wear resistance can be improved without deteriorating the bonding strength of the matrix of the Al alloy.
