Properties of sulfidized iron-graphite materials at high rubbing velocities

The authors have investigated the properties of sulfidized iron-graphite materials in unlubricated friction at rubbing velocities of 22, 35, and 52 m/sec and loads of 0.68 and 1.3 daN/cm2. The results of these tests have demonstrated the suitability of such materials for operation at high rubbing velocities, low loads, and short service times.
