摘要
In this paper, a nanosecond laser was used to etch the surface of graphene nanoplatelets reinforced ZK60 (GNPs/ZK60) matrix composites, and the effects of different scanning speeds, pulse repetition frequency and laser power on the etched morphology of the machined surface were investigated. The experimental results show that the etched groove width and heat affected zone width of GNPs/ZK60 composites are significantly increased compared with ZK60 material due to the influence of graphene, and the growth rate of the difference in heat affected zone width between GNPs/ZK60 composites and ZK60 materials is most significantly affected by the pulse repetition frequency. In addition, the dross height increases with the increase of laser power, while the scaly dross structure becomes increasingly clear. Laser processing is a very efficient and energy saving processing method for graphene-reinforced magnesium matrix composites. In order to study the phenomenon of nanosecond laser processing of graphene-reinforced magnesium matrix composites, the effects of nanosecond laser processing on graphene-reinforced magnesium matrix composites are described from four perspectives. image
