Abstract: (3455 Views)

One of the problems for use of rubber in various industries is surface tension at the surface of rubbers, which results in the crack on the surface, fracture of the rubber and reduces its life. These tensions are caused by contacting the rubber component with the metal surface and the friction between two surfaces. Roughness of the surface, the composition of the rubber compound, the environmental factors, test conditions and etc. affect the friction between rubbers – metal. Surface roughness plays an important role in sliding between two surfaces and mainly controls friction behavior. On the other hand, roughness effect on the coefficient of friction is controllable using a suitable lubricant. Regarding the fuel consumption in the industry and the characteristics of self-lubricant of the most lubricants, in the present study, the effect of JP10 & Dmaz fuels as a lubricant was investigated to reduce the sliding friction coefficient between the NBR and aluminum surfaces with different roughness. Experimental studies showed friction coefficient has a good correlation with the mean surface roughness (Ra). By applying JP10 & Dmaz fuels as lubricant, the coefficient of friction decreased by about 65% & 85%, respectively. .
