摘要：

A Ni-coated graphene (Ni-Gr) reinforced Inconel 625 composite was prepared by selective laser melting. The microstructure of the composite exhibited random aligned columnar dendrites due to the addition of Ni-Gr. The Ni-Gr defects were alleviated under high-intensity laser-beam irradiation. The Micro-CT showed that the pore density increased by 46% of Inconel 625 due to the addition of Ni-Gr. The flaky, open-ring NiGr appeared due to the action of Marangoni convection and the surface tension. Furthermore, the addition of Ni-Gr improved the diffusion capacity of the friction heat. Inconel 625 composite displayed tiny bits of oxidized debris. (c) 2021 Elsevier B.V. All rights reserved.
