Abstract To overcome two critical deficiencies i.e. poor self-lubricating and short life of engine bearing, a CuSn10 layer along with newly designed h-BN/graphite coating is deposited on the surface of an engine bearing. The tribological and mechanical properties of the engine bearing are studied. Firstly, the porosities of the CuSn10 layer and h-BN/graphite coating are low due to the powder-filled action and the sealing action of the modified polymer respectively. Secondly, the CoFs of the engine bearing under the coating of h-BN/graphite will fall by 225.00% at room temperature and 857.14% at 200 °C due to the transfer film generated. Lastly, the life of this bearing has increased by 639.03% due to the newly designed layer and coating.

不同温度下喷涂CuSn10层和h-BN/石墨涂层发动机轴承的摩擦学和力学行为

摘要 为了克服发动机轴承自润滑性差和寿命短这两个关键缺陷，在发动机轴承表面沉积一层CuSn10和新设计的h-BN/石墨涂层。研究了发动机轴承的摩擦学和机械性能。首先，由于改性聚合物的粉末填充作用和密封作用，CuSn10层和h-BN/石墨涂层的孔隙率较低。其次，由于产生了转移膜，h-BN/石墨涂层下发动机轴承的CoFs在室温下会下降225.00%，在200°C下会下降857.14%。最后，由于新设计的层和涂层，该轴承的寿命增加了 639.03%。
