Abstract:
Binderless tungsten carbides (BTC) have attracted the attention of both academia and industry due to their excellent hardness, high-temperature strength as well as corrosion resistance. Herein, a set of binderless WC-based composites were developed employing two-step spark plasma sintering. The mechanical response together with tribological performance was investigated as a function of various reinforcements including SiC whisker (SiCw) and multilayer graphene (MLG). The results suggested that the coupling and synergy of MLG and SiCw played a critical role in microstructure refinement and homogenization, consequently advancing the mechanical and tribological properties of BTC. The MLG-SiCw/BTC displayed the optimal comprehensive performances, and the associated toughening and anti-friction mechanisms were determined and analyzed. Such material design offers an effective approach to enhance the mechanical and tribological responses of ceramic materials. © 2022 Elsevier Ltd
