| Abstract: | Microstructure and properties of 4Cr13 arc spraying coatings were studied.The coatings were prepared by three surface pretreatment processes such as sandblasting,spraying base coating and electrospark roughening.Microstructure and fracture morphology of coatings were investigated by means of scanning electron microscopy(SEM) and energy dispersive spectrometry(EDS),microhardness and bonding strength were also tested.The results show that 4Cr13 coatings display the typical layer structure.Different surface pr... |
