| Abstract(E) | Engine bearings are used in high unit load and thinner oil film thickness, and seizure of the engine bearings by the contamination is concerned. Seizure resistance is confirmed by using the rig test which can simulate the seizure by scratches. Detailed observation results, polymer coating disappear at the ridge of scratch, and the lining material is exposed. The seizure of engine bearings occurs near the scratch, and the exposed lining material exists at this position. It was found that the coating material to which barium sulfate was added covered the lining mostly, and substances derived from engine oil were also attached. As a result, seizure resistance against contamination was improved. Durability tests of the coating material containing barium sulfate are performed and it is confirmed that there was no problem overall. |
