用适量Fe、Ni、Mn、Co、Be、Zn元素制备了一种多元铝青铜耐磨合金,用XRD、SEM等对试验合金的铸态和固溶时效状态下的组织进行了观察和比较,并在MMW-1型万能磨损试验机上对合金在干摩擦和油润滑条件下进行了摩擦磨损试验。结果表明,多元铝青铜合金热处理态(960℃×2 h固溶+520℃×3 h时效)的显微组织由β’、γ2和κ相组成,其摩擦因数低于铸态,油润滑条件下具有良好的耐磨损性能。
A multi-element aluminum bronze wear-resistant alloy was prepared by using proper Fe, Ni, Mn, Co, Be and Zn elements. The microstructure of the alloy was observed and compared by XRD, SEM and so on. The friction and wear tests of the alloy under the conditions of dry friction and oil lubrication were carried out on a MMW-1 universal abrasion tester. The results show that the microstructure of the multi-aluminum bronze alloy in heat treatment state (960 ℃ × 2 h solid solution + 520 ℃ × 3 h aging) consists of β ’, γ2 and κ phases, and its friction coefficient is lower than that of as-cast and oil-lubricated Under the good wear resistance.
