| Abstract: | Bearing ring driving chain for discharging ash on burning coal boiler abruptly rupture in operation. A spot investigation was conducted and a sample taken to inspect. Cracking failure of a bearing ring is analyzed by means of optical metalloscope (OM) and scanning electron microscopy (SEM), in light of chemical composition, microstructure and property. The result shows that it is a typical over-wear and fretting fatigue cracking. |
