摘要：
The film forming behavior has been investigated under oil-air lubrication, compared with that under oil-jet lubrication in present work. Images of microscopic oil reservoir and interference were obtained up to 30 m/s. A parameter eta describing the oil supply effects is 30 times higher and the film thickness reduces in starved regime much slower under oil - air lubrication compared with that under oil-jet lubrication. The contribution of micron-order oil droplets on film forming is discussed. More micron-order oil droplets can spread onto the disc while less of them are driven away by centrifugal effects. As a result, the oil supply efficiency of oil - air lubrication is improved. The high pressure compressed air can blow off the oil and intensify the film oscillation. (C) 2015 Elsevier Ltd.
