Wear Behavior Of Chromizing-Titanizing Coating

Abstract:

The wear behavior of chromizing-titanizing coating is examined in different media at room temperature and at elevated temperature, and compared with the wear behaviors of chromizing coating, titamizing coating and basis carbon steel. The structure of chromizing-titanizing coating is analyzed using electron probe, X-ray diffration and hardness. The results show that the chromizing-titanizing coating has better wear resistance than that of chromizing coating, titanizing coating and basis material. The wear resistance of chromizing-titanizing coating is mainly affected by the microstructure and composite of the coating which consists of complex compounds containing chromium carbides and TiC. The chromizing carbides exist mainly outside the coating and TiC exists mainly inside the coating. The complex compounds make the coating have both advantages of chromizing coating and titanizing coating, resulting in good wear resistance of chromizing-titanizing coating at room temperature and at elevated temperature.
