A cylinder liner for internal combustion engines has an outer roughened surface that has particularly good adherence properties. The surface has is covered with protrusions or spines of varying shapes and sizes, which are created by spraying the mold with a coating and then casting the cylinder liner in the mold. The spines are generally conical or needle-shaped, with the bases being larger than the tips. The spines have an aggregate cross-sectional surface area measured at 0.2 mm from a ground cylindrical surface that is between 50-90% of the total ground cylindrical surface area, and an aggregate cross-sectional surface area measured at 0.4 mm from the ground cylindrical surface that is between 20-45% of the total ground cylindrical surface area. 种用于内燃机的气缸衬套，其具有外粗糙表面，外粗糙表面具有特别良好的粘接属性。该表面被具有可变形状和尺寸的突起或者突脊覆盖，其通过喷射具有涂层的模具创建，然后铸造模具中的气缸衬套。突脊大致为锥形或者针状，基底大于末端。突脊具有的在距基面气缸表面0.2mm处测量的总体截面表面积为总基面气缸表面面积的50-90％之间，以及在距基面气缸表面0.4mm处测量的总体截面表面面积为总基面气缸表面面积的20-45％之间。
