In order to study the effect of Ta layer on the corrosion resistance of the alloy surface, the diffused layer was prepared on the 34CrNi3Mo steel surface by double glow plasma infiltration. The surface morphology, phase structure, element distribution, hardness change and the adhesion between the infiltrated layer and the substrate were investigated. The ablation property and corrosion resistance of Ta layer were analyzed. The results show that Ta layer is mainly composed of BCC α-Ta composition with the deposition layer depth of about 10μm and diffusion layer depth of about 3μm. The surface layer hardness is about 500HV0.2 and the bonding strength is about 65N. Under the same working condition, the corrosion resistance of Ta layer is better than that of matrix, which can prevent the formation of the embrittlement between C/N and matrix. With the increasing numbers of pulse ablation, the ablation area increases but the ablation depth maintains shallow. In the case of the high power pulse ablation, the Ta layer can decrease the melting and vaporization process, and improve the ablation resistance of the matrix.
