| 摘 要： | 采用燃烧反应工艺焊接了TiB2陶瓷与金属Mo,对中间反应层生成物进行了XRD物相分析,对焊接界面结合情况进行了电子探针分析。温度和中间层组分对焊接件的抗弯强度和抗剪切强度有一定的影响。分析表明:抗弯强度在焊接温度为1500℃,中间层Mo含量为80wt%时达最大值;在焊接温度为1500℃,中间层组分中含Mo为40wt%时所得焊接件抗剪切强度值达最大。

| Abstract: | Combustion reaction welding technique was used for welding TiB2 and metal(Mo). The results showed that the main products of combustion reaction were TiB2 and MoB. When the content of Mo in intermediums was over 60 wt%, Mo would be surplus. Temperature strongly affected samples properties. When the sample was welded at 1500 ℃ with 80 wt% Mo in the intermedium, the value of bending strength was the largest. The largest value of shear strength among all the samples was the one welded at 1500 ℃ with 40 wt% Mo in the intermedium. |
