“…The wear tests of the composites were performed by using a ball-on-block high temperature tribometer in dry sliding against a 9.53 mm Al 2 O 3 ball [10]. The Al 2 O 3 balls were used in the as-received condition with a surface roughness of 0.02 µm (Ra), a hardness of 16.5 GPa and a density of 3.95 g/cm 3 .…”

ZrO2(Y2O3)-Al2O3-SrSO4 nanocomposites incorporated with and without Ag addition have been fabricated by spark plasma sintering (SPS) to evaluate their friction and wear properties in sliding against alumina ball from room temperature to 600 oC. X-ray diffraction (XRD), scanning electron microscope (SEM) and Raman spectroscopy were used to investigate microstructure and self-lubrication mechanisms of nanocomposites after wear tests at different temperatures. The ZrO2(Y2O3)-Al2O3-SrSO4 nanocomposite exhibits low and stable friction coefficients of 0.2 to 0.3 and wear rates in the order of 10-6 mm3/Nm at high temperatures. With the addition of Ag into the composite, the intermediate temperature lubricating property is greatly improved. Plastic deformation of SrSO4 and sliver during sliding plays an important role in formation of lubricating films on worn surfaces of nanocomposites. These lubricating films reduce the friction and wear of the ZrO2(Y2O3)-Al2O3 matrix composites.

Spark plasma sintering (SPS) is employed to fabricate the self-lubricating Al 2 O 3 -SrSO 4 nanocomposites by tailoring the chemical compositions. Their friction and wear properties have been evaluated using a high temperature friction and wear tester from room temperature to 600 in dry sliding against alumina ball. Nanosized SrSO 4 powders were synthesized by chemical precipitation process at room temperature and atmospheric pressure. For a comparative study, SrSO 4 solid lubricants with different particle sizes are intentionally designed to investigate the influence of size effect on self-lubricating properties of Al 2 O 3 -SrSO 4 nanocomposites under the identical test conditions. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to investigate microstructure and self-lubrication mechanisms of nanocomposites after wear tests at different temperatures. Al 2 O 3 -SrSO 4 nanocomposites with optimum compositional combinations exhibit low and stable friction coefficients of 0.18 to 0.29 and wear rates in the order of 10 -3 to 10 -5 mm 3 /Nm at high temperatures. With increasing test temperature, plastic deformation of SrSO 4 during sliding plays an important role in formation of lubricating films on worn surfaces of nanocomposites. These lubricating films reduce the friction and wear of the Al 2 O 3 -SrSO 4 nanocomposites.
