摘要/Abstract

摘要：

碳化硅(SiC)陶瓷具有优异的力学性能, 但是其断裂韧性相对较低。石墨烯的引入有望解决碳化硅陶瓷的断裂韧性较低的问题。本研究采用热压烧结工艺, 制备了具有不同还原-氧化石墨烯(rGO)掺入量的SiC复合材料。经过2050℃保温、40 MPa保压1 h后, 所制备的复合材料均烧结致密。对复合材料中rGO的掺入量、微观结构和力学性能的相互关系进行分析和讨论。加入4wt%的rGO后, 复合材料的三点抗弯强度达到564 MPa, 比热压SiC陶瓷提高了6%; 断裂韧性达到4.02 MPa•m^1/2, 比热压SiC陶瓷提高了54%。加入6wt%的rGO后, 复合材料的三点抗弯强度达到420 MPa, 略低于热压SiC陶瓷, 但其断裂韧性达到4.56 MPa•m^1/2, 比热压SiC陶瓷提高了75%。裂纹扩展微观结果显示, 主要增韧机理有裂纹偏转、裂纹桥连和rGO片的拔出。

Abstract:

SiC ceramics have excellent mechanical properties, but its toughness is relatively low. To enhance the fracture toughness of SiC ceramics, graphene is introduced as fillers. In this study, the silicon carbide-reduced graphene oxide (SiC/rGO) composites with different contents of rGO were fabricated by hot press sintering (HP). Near fully-dense SiC/rGO composite was obtained after being hot-pressed under 2050℃, 40 MPa for 1 h. In addition, the influences of graphene reinforcement on the sintering process, microstructure, and mechanical properties (fracture toughness, bending strength, and Vickers hardness) of SiC/rGO composites were discussed. The three-point flexural strength of 4wt% rGO/SiC composite reached 564 MPa, and the fracture toughness reached 4.02 MPa•m^1/2, which were 6% and 54% higher than those of hot-pressed SiC ceramics, respectively. The flexural strength of the three points of 6wt% rGO/SiC composite was 420 MPa, which was lower than that of hot-pressed SiC ceramics. While its fracture toughness was up to 4.56 MPa•m^1/2, which was 75% higher than that of hot-pressed SiC ceramics. The results of crack propagation show that the toughening mechanism can be ascribed to crack deflection, crack bridging and rGO pullout.
