초록
The study focused to explore the effect of graphene (rGO) (0.3 wt.%) inside the yttria-stabilised zirconia (YSZ) matrix in termsof mechanical and functional properties. The samples were developed through the powder metallurgy route. The requisiteamounts of powders were uniaxially pressed in disc shapes having 20 mm diameter and sintered at 1350 °C for half an hourin HT furnace. The sintered samples were thoroughly polished till the average surface roughness reached to 0.5 micron. Themicrostructure analysis revealed that the presence of graphene acts as a grain refiner result in homogeneous structure of grainmorphology throughout the structure. Additionally, the presence of graphene significantly improved fracture toughness by21% without compromise in hardness. The improvement was attributed to the refinement in gain morphology accompaniedby crack bridging or deflection. The functional analysis revealed that the co-efficient of friction for 0.3 wt.% rGO inside YSZimproved by 20% compared to simple YSZ. A thin film formation (transfer film) developed between the interacting materialsis responsible for the improvement in the co-efficient of friction. Hence, the developed ceramics that have excellent fracturetoughness and tribological properties may suitably applied for production of ceramic seals.
