摘要: 对比分析了氧乙炔焊和氩弧焊两种焊接方法下,热处理前后1Cr16Ni4Mo2Cu2W1VN钢表面Co6B堆焊层的组织性能,探究焊接工艺对1Cr16Ni4Mo2Cu2W1VN钢与Co6B合金相容性的影响。结果表明,1Cr16Ni4Mo2Cu2W1VN钢与Co6B合金具有良好的相容性。较氩弧焊堆焊层,氧乙炔焊堆焊层熔合过渡区宽,硬度较氩弧焊堆焊层高7.3 HRC。经固溶+深冷+回火热处理后,氧乙炔焊堆焊层致密,组织细小、均匀,硬度45.3 HRC,冲击吸收能量84.7 J,表现出更优的综合性能。

Abstract: Microstructure and properties of Co6B surfacing layer on the surface of 1Cr16Ni4Mo2Cu2W1VN steel before and after heat treatment were compared and analyzed under the two welding methods of oxyacetylene welding and argon arc welding, and the effect of welding method on the compatibility of the 1Cr16Ni4Mo2Cu2W1VN steel and Co6B alloy was explored. The results show that the 1Cr16Ni4Mo2Cu2W1VN steel has good compatibility with the Co6B alloy. Compared with the argon arc weld surfacing layer, the fusion transition zone of the oxyacetylene weld surfacing layer is wider, and the hardness is 7.3 HRC higher than that of the argon arc weld surfacing layer. After solid solution+cryogenic treatment+tempering, the oxyacetylene weld surfacing layer is dense, with fine and uniform structure, hardness of 45.3 HRC, and impact absorbed energy of 84.7 J, exhibiting better comprehensive performance.

Key words: oxyacetylene welding, argon arc welding, 1Cr16Ni4Mo2Cu2W1VN steel, Co6B alloy surfacing layer, compatibility, properties
