内燃机轴瓦涂层的研究现状

Investigation Status of Coatings for Bearing Bush of Internal Combustion Engine

轴瓦是内燃机中的关键零件,提高轴瓦的自润滑性是延长内燃机使用寿命的有效方法。介绍了电镀镀层、磁控溅射薄膜、固体润滑涂层等内燃机轴瓦涂层的研究进展,并从环保、生产效率、耐磨性、成本等方面对三种轴瓦涂层进行了对比。

The bearing bush is a key part in the internal combustion engine,improving the self-lubricating property of the bearing bush is an effective method to extend the service life of the internal combustion engine.The research progress of the coatings for bearing bush of internal combustion engine such as electroplated coating,magnetron sputtering film,solid lubricating coating,etc.was introduced,and three types of coatings for the bearing bush were compared from the aspects of environmental protection,production efficiency,wear resistance and cost.
