“…The fracture toughness of the pure NiO matrix was 5.12 ± 0.34 MPa • m 1/2 , which agrees with the previously reported value (5.2 ± 0.8 Mpa • m 1/2 ) evaluated via the VAMAS procedure on pre-notched specimens [27]. The fracture toughness of the composites decreased with increasing GDC contents, however, all these values were higher than that of GDC (1.27 ± 0.13 Mpa • m 1/2 ) [22].…”

The tribological performance and friction-induced vibration of Gd0.2-Ce0.8O1.9 (GDC) reinforced nickel oxide (NiO) metal matrix composites prepared via sintering on the tribological performance, as well as friction induced vibration were investigated. Compared to pure NiO, the composites exhibit improved mechanical properties, such as a relatively high dislocation density, hardness and small grain size. The results show that GDC-reinforced NiO nanocomposites feature improved tribological performance and can suppress the occurrence of friction-induced vibration under variable loading conditions. Furthermore, the generated acceleration can be suppressed by wear particles generated during the friction process, acting as the third body at the contact interface. As a result, the addition of GDC reduces the grain size of the composite, increases hardness, and improves tribological properties through the synergetic effect of the solid lubricating action of NiO and the role of the third body of the wear particle.

“…Heat of combustion (flame temperature) helps in crystallization and formation of the desired phase while the gases evolved induce porosity and limit the reaction temperature and hence the particle size and surface area. The heat of combustion and gas evolution are dependent on nature of the fuel and oxidant to fuel ratio [9,10]. Therefore, among the different fuels, glycine was used since it acts as complexing agent and provides source of C and H, which on combustion form large amount of CO 2 and H 2 O with liberation of heat.…”

The 20 % yttrium doped barium cerate (BCY20) powder has been synthesized by cost effective solution combustion method. The flame temperature measured by pyrometer was 1055°C, less than the adiabatic temperature due to various losses. The phase formation and evolution was studied with TG-DTA and XRD. The carbonate free orthorhombic BCY20 phase was obtained upon calcination at 900°C. The microstructure of the powders and sintered pellet was examined through scanning electron microscopy. The vibrational mode at 355 cm, characteristics of CeO 6 octahedra, was detected in Raman while the bands corresponding to M-O vibrations were revealed in FT-IR. The dc conductivities of sintered pellet measured in argon and air atmospheres at 600°C were 1.53×10 −3 and 1.41×10 −3 S/cm.
