Frequent Start-Stop Test Study of Graphene Coatings on Journal Bearings

Article Preview

Abstract:

In this study, the graphene was prepared by chemical vapor deposition (CVD) method, and then through thermal annealing technique it was firmly coated on and partly diffused into the inner surfaces of journal bearings made from aluminum bronze CuAl10Fe3. The journal bearings without graphene coatings were also prepared with made from aluminum bronze CuAl10Fe3 and tested under the same conditions as the references of comparison. Through frequent start-stop test, the changing laws of coefficient of friction (COF), power consumption, and back temperature rise and wear loss for each journal bearing with or without graphene coating were obtained. The test results showed that graphene coating could significantly reduce the power consumption and wear loss during the start and stop phases.
