摘要
在实验中借鉴了钎焊及扩散焊工艺的一些特点,运用中间夹层材料来促进不锈钢与碳钢的复合·主要对影响复合的各种因素,包括压力、温度、保温时间、保护气体等进行了一系列的实验,摸索出了几种中间夹层材料能够发挥最佳效果的工艺参数·在采用银铜锌中间夹层材料时,通过实验总结出当复合温度为750℃,首道次压下率为25%时可以实现不锈钢与碳钢之间的良好复合·使用纯净的氩气能够有效地防止复合表面的氧化·另外从理论上较为深入地分析了各项工艺参数对复合效果的影响·
In view of the features of diffusion welding process,some interlayer materials were used to facilitate the stainless steel sheet to clad the carbonsteel sheet. A series of tests have been done to investigate various influential factors on cladding process,such as pressure,temperature and its holding time and protective gas. It is found that some interlayer materials can provide optimum technological parameters to cladding process. As tested the stainless steel sheet can be clad onto carbonsteel sheet if taking silvercopperzinc solder as interlayer or sandwiched layer for cladding at 750?℃ with 25% reduction in first pass. Pure argon has proved an effective protective gas from surface oxidation. In addition,the influence of various parameters on cladding results was also analyzed theoretically.
