چکیده

In this study, the effect of chromium carbide (Cr7C3) on abrasive wear behavior of Fe-C-Mo-FeCr composite was investigated. Composite, which was produced by a powder metallurgy route was containing 3 wt.% Mo, 1.5 wt. % C and 4,8,12 wt. % FeCr with the different particle sizes. In the experiments, wear resistance of samples were determined using different loads by a pin on disc wear tester. Microstucture of samples were examined by an optical and scanning electron microscopy, EDS and X-Ray diffraction methods. The hardnesses of samples were measured in RB scale. Finally, it has been found that with the increasing particle size of reinforcing element, wear resistance decreased and with the increasing reinforcing element, the wear resistance increased.

Evaluation of Microstructure and Wear Behavior of Iron-based Hard - facing Coatings on the Mo40 Steel

Mo40 low-alloy steels are mostly used to produce industrial components such as crane wheels which are exposed to abrasive wear. However, during working conditions, their wear resistance is reduced after a while due to its low hardness. With increasing abrasive wear, the dimensions of components decrease and they need to be repaired for surface modification. In this regard, hard overlay coatings...
