Friction and wear properties of Si3N4-hBN ceramic composites using different synthetic lubricants

This paper presents a tribological investigation of Si3N4-hBN composite ceramics using synthetic lubricants. The friction and wear properties of Si3N4-hBN ceramic composites sliding against TC4 titanium alloy (Ti6Al4V) were investigated via pin-on-disc tests. An axial compressive load of 10 N was applied with a sliding speed of 0.73 m/s. Three different lubrication conditions including simulated body fluid (SBF), physiological saline (PS) and...
