Rippling failure occurring on rollers and gears is well known as one of the phenomena resulting from plastic flow of the surface layer caused by repeated sliding-rolling contact. We have alreadyreported some experimental results on the rippling failure. The rippling failure is closely related to lubricant. In this paper, we considered how lubricants influence the rippling failure. In particular, the effects of additives of lubricating oils were investigated in detail by roller test. The oils added several additives to automotive gear oils were used as lubricant. Consequently, the following becomes clear in this paper. The coefficient of friction is related to the occurrence of rippling, and the gear oil which has higher coefficient of friction is easier to generate the rippling. For the automotive S-P type gear oil, to add the borate (dipotassium tetraborate tetrahydrate) is effective to prevent the occurrence of rippling failure.
