| Abstract: | Cermet coating was deposited by actived combustion-high velocity air fuel （AC-HVAF） technique with micro- and nano-scale NiCr/WC powder as raw material. Bonding strength of the coating was investigated based on the newest test standard. Composition distribution and micro-morphology of the tensile fracture were investigated by SEM. The result shows that the cement coating prepared by AC-HVAF has a bonding strength to the substrate of 163 MPa. |
