The tribological properties between the CuNiCr cylinder liner with different honing morphology and Cr-Al₂O₃ coated piston ring were studied. The wear surface morphology and the chemical element distribution of the CuNiCr cylinder liner as well as the effects of honing angle and roughness on the friction and wear of cylinder liner and the cylinder antiscuffing performance were analyzed. The results show that optimizing the honing angle and roughness can improve the tribological performance of cylinder liner effectively. The honing angle and roughness not only affect the wear mechanism between the piston ring and cylinder liner, but also have great influence on the distribution and maintenance of lubricating oil film, which affects its friction and wear and the cylinder antiscuffing performance.
