Some investigations on laser hardened properties and microscopic structures characteristic of automobile cylinder were conducted in this paper. The study indicates that using laser hardening can remarkably improve the hardness of cylinder. The laser hardening microscopic structures are mainly very fine martensite and the original pattern of flake graphite basically remain.
