Abstract
The tribological properties and lubrication mechanisms of oil need extensive performance on a textured surface. Despite this, the lubrication of grease on textures surfaces is considered as new. This report will present an experimental study of grease in frictional behaviors with lubricated sliding contact under mixed conditions. The experiment is conducted by using a 4-ball tester machine with ASTM D2266 with influences surface texture parameters on frictional properties. The results give the friction coefficient is mostly reliant on texture parameters and density. The test is conducted with greases formulation of the different additives. The aim is to suppress the best friction properties in all experimental conditions which can accumulate more grease and trap wear debris. The reduction friction is attributable to the formation of a stable grease lubrication film composed of the oil film and the hydrodynamic pressure effect of the surface texture. This property demand to increase the mating gap and reduces the probability of asperity contact. This result will help in understanding the tribological behavior of grease on a textured surface and predict the lubrication conditions of sliding bearings for superior operation in machinery
