Title (EN) ALUMINUM-BASED ALLOY BEARING
(FR) PALIER EN ALLIAGE A BASE D"ALUMINIUM
Abstract: front page image
(EN)An aluminum alloy containing 2.5 to 25 wt.% tin, 0.5 to 8 wt.% zinc, 1 to 7 wt.% of at least one element selected from the group consisting of silicon, chromium, manganese, nickel, iron, zirconium, molybdenum, cobalt, tungsten, titanium, antimony, niobium, vanadium, cerium, barium, and calcium, and the balance substantially aluminum. The 1 to 7 wt.% silicon or the like may be replaced by 0.1 to 1 wt.% (1 wt.% exclusive) chromium. This alloy eliminates the defects of deterioration of high temperature hardness and fatigue resistance with conventional alloys when formed into a bearing by pressure-welding a tin-containing aluminum alloy onto backing steel, due to coarsening of aluminum crystal particles and tin precipitates in the alloy structure. This may be used as a bearing in the crankshaft of an automobile.
(FR)Un alliage d"aluminium contenant 2, 5 a 25% en poids d"etain, 0, 5 a 8% en poids de zinc, 1 a 7% en poids d"au moins un element selectionne parmi le groupe constitue de silicium, chrome, manganese, nickel, fer, zirconium, molybdene, cobalt, tungstene, titane, antimoine, niobium, vanadium, cerium, baryum et calcium, le reste etant constitue sensiblement d"aluminium. La quantite de 1 a 7% en poids de silicium ou autre peut etre remplacee par 0, 1 a 1% en poids (a l"exclusion de 1% en poids) de chrome. Cet alliage elimine les defauts de deterioration de la durete et de la resistance a la fatigue a haute temperature que l"on constate dans les alliages conventionnels lorsqu"ils sont utilises pour former un palier par soudage a pression d"un alliage d"aluminium contenant de l"etain sur un support d"acier, a cause du grossissement des cristaux d"aluminium et de la precipitation dans la structure de l"alliage. Cet alliage peut etre utilise pour un palier d"un vilbrequin du moteur d"une voiture.
