| 中文摘要: |
| 为明确不同合金元素在堆焊金属中的作用，设计了12种碱性药皮堆焊焊条，利用光电直读光谱仪、洛氏硬度计对堆焊金属的成分及硬度进行了测试，分析了C、Ti、Nb、V的合金过渡特点及其对堆焊金属硬度的影响规律。结果表明：C元素过渡波动较大，Nb、V过渡较稳定，各种元素的过渡相互影响；C、V固溶强化作用大，能够提高堆焊金属硬度，而Ti、Nb主要形成碳化物，含量过多时会减弱碳的固溶强化作用，使硬度降低。 |
| 英文摘要: |
| To make clear the effect of different alloy elements in the deposited metal, 12 species of basic coated electrode were prepared, and the chemical constitution and hardness of their surfacing welded metal were tested, then the alloy transfer character of C, Ti, Nb and V, and their effects on the hardness were discussed. It is indicated that the transfer of different alloy elements influences each other, the transfer efficiency of carbon is unstable while that of Nb and V are more stable. The C and V in the welding metal has strong solid solution strengthening effect, then can increase the hardness, but the raising of Ti and Nb content decreases the hardness due to the formation of too much carbides. |
