A research on detonation gun coating with Fe–SiC composite powders mechanically activated

The Fe–SiC composite powder prepared by the mechanical activation process has been used for coating on materials with the detonation gun (D-gun) machine in order to develop a new way for coating. It has been found that the coating layer has fine, homogeneous, dense structure and good wear resistance. The results of SEM and X-ray diffraction (XRD) show that some reactions happened between Fe and SiC during the D-gun coating, the Fe–Si compounds formed and SiC strength the coating layer. It has been proved that the technology combined mechanical alloying with D-gun coating is a new method for surface modification.
