| Abstract: | Specialities of and effects on laser case hardening are analysed and, meantime, technological investigation inlaser hardening for a high-power diesel liner targeted is presented. As shown in the paper, through performance analysisconducted for the treated work piece, it was found that its hardness, microstructure, wearability and fatique resistance havebeen improved similarly; and based on experiments, the optimal technology for laser case hardening of cylinder liner likecomponents has been confirmed. |
