Enhanced Frictional Properties of NiO-Based Nanocomposites with the Addition of GDC

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 performance, as well friction induced were investigated. Compared to pure NiO, exhibit improved mechanical properties, such a relatively high dislocation density, hardness small grain size. results show that GDC-reinforced NiO nanocomposites feature can suppress occurrence under variable loading conditions. Furthermore, generated acceleration be suppressed by wear particles during process, acting third body at contact interface. As result, addition GDC reduces size composite, increases hardness, improves properties through synergetic effect solid lubricating action role particle.
