【摘要】Because of their severe working environment,durability of AISI H13 hot-working tool steels used for producing parts of Al alloys and Mg alloys is poor.Hence,based on the introduc-tion of recently developed surface-modified technologies for the steel,laser-heated quenching pro-cessing is considered to be applied widely in engineering field due to its combined advantages of enhanced surface performance,low residual stresses and high bonding between the surface and the substrate,whereas laser cladding processing is considered to present a high potential in application due to its surface designability and employment reliability.Despite the advantages of short route and coating designability in thermal spraying,the bonding of the coating with the steel substate is j ust poor.So thermal spraying has to follow a suitable thermal match design between the coating and the substrate.In conclusion,the surface-modified products by thermal spraying can meet the combined requirements of high performance and high durability.%用于加工铝合金、镁合金零部件的 AISI H 13热作模具钢因其恶劣的服役环境,现已表现出低寿命的致命缺陷。激光加热淬火工艺因兼有表面强化、残余应力低及与基底保持高的结合之特性,使 AISI H 13热作
