在铝合金的生产中,出现的结构组份越来越多,其目的是降低合金的重量并增进其全面的性能。总的来说,传统的高硅铝合金在充分润滑的情况下有良好的抗磨损性能。在许多应用中润滑都通常不足,加上润滑膜的损坏,可能产生强烈的摩擦和滞塞。一大半汽车结构零件都是用压铸法制造的。这些 In the production of aluminum alloys, there are more and more structural components, the purpose is to reduce the weight of the alloy and to enhance its overall performance. In general, the conventional high-silicon aluminum alloy has good wear resistance under fully lubricated conditions. Lubrication is often inadequate in many applications. Coupled with damage to the lubricant film, strong friction and seizure may occur. Most of the car structural parts are made by die casting. These ones
