滑动轴承作为发动机的重要动力传输部件,轴承质量对发动机性能起至关重要的作用。介绍轴承的三种减磨合金材料:巴氏合金、铜基合金、铝基合金,通常铝基轴承会在材料上电镀一层过渡层来解决铝合金本身存在的问题。讨论了国内外DLC薄膜在滑动轴承上研究和应用状况,针对在铝基合金上镀膜存在较大应力的现象,提出镀过渡层,热退火处理和DLC薄膜中掺杂元素的方法来缓解应力。随着人们对发动机性能越来越高的要求,以及保护环境的需求,DLC薄膜在发动机轴承上有着巨大的发展前景。 As an important power transmission component of the engine, the bearing quality plays an important role in engine performance. Describe the three bearing wear reduction alloy materials: Babbitt, copper-based alloys, aluminum-based alloys, aluminum bearings are usually plated on the material layer of transition layer to solve the problems inherent in the aluminum alloy. The research and application status of DLC films on sliding bearings at home and abroad are discussed. In order to relieve the stress of plating on Al-based alloy, some measures are proposed to deal with the phenomena such as transition layer, thermal annealing and doping elements in DLC films. As people demand higher and higher engine performance, as well as the need to protect the environment, DLC film has a huge development prospect in the engine bearing.
