Nghiên Cứu Chế Tạo Vật Liệu Compozit Nền Đồng Gia Cường Bằng Vật Liệu Graphen Sử Dụng Phương Pháp Luyện Kim Bột

Copper/graphene (Cu/Gr) composite materials containing 1%vol. graphene (Gr) was successfully fabricated by powder metallurgy method using isostatic hot pressing technique. The morphological and structural analysis showed that the composite material has a relatively homogenous structure. The influence of Gr reinforcement on the mechanical properties and wear behavior has been studied. Experimental results show that when the Gr component is reinforced, the hardness and tensile strength of Cu/Gr composite increase by 46% and 79% higher than that of Cu, respectively. Similarly, the coefficient of friction and wear rate of Cu/Gr composite materials are reduced to 28% compared to Cu materials. Thus, the Gr material has demonstrated the ability to improve the mechanical properties and wear resistance of Cu-based composites. This result opens up the applicability of this composite in applications in modern industries such as automobiles, electricity, and electronics.
