This paper mainly presents a method of CoNi-based alloy powder preparation and performance of the sprayed coating. The phase analyze and surface morphology of CoNi-based alloy,powder and coating are tested by XRD, SEM and EDS respectively. The results show that casting alloy is composed of dendritic phase, without obvious element segregation. The alloy powder is spherical and the micro-hardness and bonding strength of the coating are 450HV0.3 and 50Mpa respectively.
