摘要：
The effects of surface roughness on the seizure limits of EP oils were examined by two-cylinder tests. In the lower range of specific slidings where the seizure tends to take place in boundary lubrication, the seizure limits are little affected by the surface roughness and are high. On the other hand, in the higher range of specific slidings, most seizures take place in mixed or full EHD lubrication and they are low. The load carrying capacities of EP oils with less chemical reactivities markedly decrease as the surface roughness is increased. Therefore, it is necessary to make clear the mechanism of the seizure occurrence in mixed or full EHD lubrication considering the interference among projections, specific sliding, and bulk temperature.
