对不同堆焊工艺及不同热处理工艺下，12Cr2Mo1R钢板上带极堆焊镍基276（NiCrMo-4钢）的化学成分、晶间腐蚀性能、力学性能、显微组织等进行了分析，研究了镍基276的最佳堆焊工艺及热处理工艺。结果表明：先在12Cr2Mo1R钢板上堆焊309L钢（过渡层）/NiCrMo-3钢（中间层），然后对其进行（690±14）℃，32 h的模拟焊后热处理，最后堆焊表层镍基276，可以使钢板获得较低的腐蚀速率、较好的力学性能和显微组织。

The chemical composition, intergranular corrosion performance, mechanical properties and microstructure of nickel-based 276 (NiCrMo-4 steel) strip overlap welding on 12Cr2Mo1R steel plate were analyzed under different surfacing processes and different heat treatment processes, the optimum surfacing process and heat treatment process of nickel-based 276 were studied. The results show that 309L steel (transition layer)/NiCrMo-3 steel (intermediate layer) was first deposited on 12Cr2Mo1R steel plate, and then simulated post-weld heat treatment was carried out at (690±14)℃ for 32 h, finally, nickel-based 276 was deposited on the surface of the steel plate, so that the steel plate had lower corrosion rate, better mechanical properties and microstructure.
