摘要: Abstract The effect of ball diameter on wear and friction a molybdenum disulphide (MoS2) coating deposited using the closed-field magnetron sputtering technique has been investigated ball-on-disk rig sliding against uncoated steel ball-bearing balls. It was observed that rate decreased significantly with increase in diameter. Correspondingly, average coefficient steady state increased Under present experimental conditions, size vanished when exceeded 6.35 mm. This phenomenon is thought to be result mode transition as function contact pressure at apparent area from low-rate ‘mild’ regime high-rate ‘severe’ exceeds some critical value. Simulation results previously presented model based above assumption showed good agreement observations.
