Effects of Micropit Depths on Tribology Performance of Textured Port Plate Pair
Published 2018-01-01“…The conclusions are shown as follows: oil loading capacity would come to its peak when the oil film thickness is equal to the micropit depth; the optimal micropit depth is unrelated to the area ratios and micropits’ diameters. With the same parameters, the effects of antifriction is optimal when the micropits’ depth is 10 μm, while antiwear and surface integrity are optimal when 15 μm. …”
