对球墨铸铁激光表面重熔／快速凝固组织进行热处理，使亚稳相快速凝固共晶渗碳体部分转变为石墨，成功地制得了既含快速凝固共晶渗碳体又含弥散石墨的新型多相铁基耐磨材料其中渗碳体及石墨相的体积分数可以通过调节退火时间严格控制由于集中了快速凝固共晶渗碳体的优异耐磨性与弥散石墨相的优异自润滑、传热及减振性能，它是干摩擦及边界润滑等工况下较理想的摩擦学材料
The ductile iron laser surface remelting / rapid solidification microstructure of the heat treatment, the rapid solidification of metastable phase eutectic cementite part of the graphite, successfully obtained both rapid solidification eutectic cementite and a new type of dispersed graphite Phase iron-based wear-resistant materials in which the volume fraction of cementite and graphite phase can be strictly controlled by adjusting the annealing time due to focus on rapid solidification eutectic cementite excellent wear resistance and dispersed graphite phase excellent self-lubricating, heat transfer and Vibration damping performance, it is dry friction and boundary lubrication conditions such as the ideal tribology materials
