The wear behaviors of yttria-doped tetragonal zirconia polycrystal (Y-TZP) ceramics with different microstructures worn against diamond wheel under various wearing conditions were investigated and compared to that of dense magnesia-doped partially stabilized zirconia (Mg-PSZ) and fine-grain Al 2 O 3 . A block-on-wheel tribometer with unidirectional sliding was used to carry out the...
Carbon nitride (β-C 3 N 4 ) films were successfully deposited onto Si (100) and WC cermet substrates by unbalanced magnetron sputtering. Reactive deposition was performed by using a graphite target in an Ar/N 2 plasma. The films were characterized by X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM),...
To research and develop water-based lubricants suited for use in ceramic tribocouples is very important for the successful use of ceramics in aqueous environments. A block-on-ring tester was used to investigate the effect of some water-based lubricants on Cr 2 O 3 coating/Cr 2 O 3 coating contacts at ambient conditions. Relative to water, lithium stearate and magnesium...
