The Effect of Sulfuration on Wear Behavior of NBR under Water Lubricating Sliding

Abstract:

Surface modification treatment on rubber used in lubricating environment can reduce the friction coefficient, friction temperature and wear loss, thereby increase the service life of rubber products. The effect of Sulfuration treatment on wear behavior of NBR was investigated using a reciprocating tester under water lubricating sliding. The hardness and morphology of samples were measured using Shore sclerometer and stereo microscope, respectively. The results showed that immersion loss of rubber in different sulfuration solution increased with immersion time. The immersion loss of rubber immersed in 60% and 70% sulfuration solution remarkably increased after immersing for 4 and 3 days, respectively. The Shore hardness of rubber immersed in sulfuration solution was higher than that untreated sample. The Shore hardness of rubber increased with the increasement of sulfuration concentration and immersing time. Better resistance of NBR in water lubricating sliding could be obtained when NBR is immersed in lower sulfuration solution for longer time or in high sulfuration solution for shorter time.
