摘要：
The composites integrated of graphene and 316L (graphene/316L) was successfully fabricated by using laser deposited additive manufacturing (LDAM). And the mechanisms of graphene reinforcement are explored. The microstructure, the phase and the mechanical properties was tested. And the result showed that the multilayer-graphene survived and distributed uniformly during LDAM. As the added graphene is 2 wt%, the mechanical properties of composites, such as tensile strength, microhardness and friction-wear properties are 5.44%, 44.91%, 76.32% better than pure 316L, respectively.
