Abstract
The present invention relates to a cylinder liner and a method of manufacturing the cylinder liner. A cylinder liner according to the present invention has an outer surface covered by casting metal when a cylinder block is manufactured by integral casting, in which a plurality of engraved grooves is formed throughout the outer surface of the cylinder liner to increase bonding force between the casting metal and the outer surface of the cylinder liner. Further, a method of manufacturing a cylinder liner according to the present invention includes: coating a coating material onto the inner circumferential surface of a mold rotating and drying the coating material for a predetermined time; applying an engraved-groove forming material to engrave the surface of the coating material; forming a cylinder liner parent body by pouring and solidifying molten metal through the surface of the coating material where the engraved-groove forming material is applied; and roughening the outer surface of the cylinder liner with a plurality of engraved grooves for spraying, after drawing the cylinder parent body out of the mold and removing the coating material and the engraved-groove forming material covering the outer surface of the cylinder liner parent body.
