Determination of oil demand for textured surfaces under conformal contact conditions

Higher dimples density resulted in small force fluctuation, smaller coefficient of friction and four times smaller oil demand compared to untextured disc or disc with smaller dimples density. Tribological performances of discs with smaller dimples density were better than those with untextured samples. The tribological behaviour of assembly with spiral dimples array was better than that with radial oil pockets layout for area density of 17%.
