%X Based on the orthogonal experiment, the effects of oxygen-fuel ratio and spraying distance on physical and mechanical properties of D-gun sprayed WC-Co coatings were investigated. An ideal coating with the uniform dense microstructures, high hardness and elastic modulus, and excellent wear resistance was obtained by technology optimization. The phase identifications and microstructure observation of the optimized WC-Co coating were conducted by XRD and SEM, respectively. The coating showed near-isotropic behaviors, which has been verified by the comparisons of mechanical and wear properties between cross section and surface. The mechanisms how the spraying parameters affected near--isotropic characters of the D-gun sprayed WC-Co coating were analyzed and discussed.
