Tribological Properties for Cast Iron CrMo at High Temperature

Abstract:

The tribological properties on the friction and wear properties of cast iron CrMo and 38CrMoAlA materials under the load, temperature, sliding speed were investigated on a MMW-1 high temperature friction-wear tester. The worn surface morphology was observed and analyzed by scanning electron microscope (SEM). The results show that considering the impact of the three factors, the conclusion was that larger influence on adhesive wear was mainly test temperature and sliding speed, the influence of the load was minimal. The main influence of test temperature and sliding speed was adhesive wear. The abrasive wear and plough cut wear were mainly caused by the load. When the synergy of the load, temperature and sliding speed reach a certain condition.
