黒鉛分散潤滑油内におけるすべり摩擦で生ずる焼付きの研究

抄録

Seizures occur when oil with solid lubricants such as graphite, molybdenum disulphide are used for sliding. The purpose of this paper is to solve the mechanism of seizures between carbon steels in oil with dispersed graphite. The main results obtained are as follows : Seizures depend on the surface roughness, that is, the smaller the roughness, the more the seizure. Friction coefficient during seizure is less than 0.25. Graphite powders dispersed in oil cause seizures due to the lack of oil at the contact between surfaces as a result of the running-in process. A minimum friction coefficient for a 5 vol.% graphite content exists.
