(Mo0.94Nb0.06)(Si0.97Al0.03)2–SiC composites were consolidated via vacuum HP sintering from the mixture of (Mo0.94Nb0.06)(Si0.97Al0.03)2 powder and SiC nanoparticles. The (Mo0.94Nb0.06)(Si0.97Al0.03)2 powder was prepared by self propagating synthesis (SHS). The effects of SiC content on the ambient temperature mechanical properties and microstructure of the SHS-HP composites were investigated. The...
In this paper, the sliding tribological performance of B4C-hBN composite ceramics with different contents of hBN against AISI 321 steel (a hard-cutting material) under distilled water condition have been evaluated using a pin-on-disc testing machine. The experiment results show that, with the increase of friction distance, the sliding friction coefficient of B4C/AISI 321 steel pair slightly decreases;...
