铝合金由于具有优异的机械性能而在多个领域获得了广泛应用,但由于其硬度低、化学活性较高而使其难于润滑。近年来,人们对铝合金的润滑进行了广泛研究[1～6],但由于试验条件不同从而得出了许多相互矛盾的结果。本文利用SRV摩擦磨损试验机研究了一种膦酸胺盐对钢铝摩擦副的摩擦? Aluminum alloys are widely used in many fields because of their excellent mechanical properties, but they are difficult to lubricate due to their low hardness and high chemical activity. In recent years, extensive studies have been conducted on the lubrication of aluminum alloys [1-6], but many conflicting results have been obtained due to different test conditions. In this paper, the use of SRV friction and wear testing machine to study a phosphonic acid amine salt on the friction of steel and aluminum friction?
