Ti-Zr-Cr-Cu-Ni and Ti-Zr-Cr-Cu-Ni-Co brazing filler metals were designed and fabricated into brazing foils by a rapidly-solidifying technique in this paper, as well as the vacuum brazing technology of Titanium alloy with 0.1mm clearance at 960℃ for 10min brazing and 900℃ for 2h diffusion treatment.The microstructure and compositions of the joints were examined and analyzed by SEM and XEDS.Meanwhile, the mechanical properties of the brazed joints were tested, and the results showed that the impact roughness and tensile strength were remarkably superior to the joints brazed with traditional Ti-Zr-Cu-Ni system filler metal.It can be expected that these new filler metals would improve the mechanical properties of those brazed titanium alloy joints for fuel pipe system in the aviation field.

对D406钢和20钢异质钢焊接接头的显微组织和力学性能进行了分析.结果表明:D406A与20钢焊缝区的显微组织主要以板条马氏体为主,熔合区主要是针状马氏体,是接头最易产生裂纹的区域;D406A一侧热影响区靠近焊缝处出现硬度最大值,其中焊缝中心为659HV0.2;20钢一侧焊接接头焊缝处的最高硬度在350HV0.2左右,低于D406A一侧焊接接头的硬度,因而D406A钢一侧热影响区的淬硬倾向相对较大
采用钴基钎料及镍基合金粉料,分别在1170℃保温10min、60min和120min的钎焊工艺下,对K452镍基铸造高温合金进行了真空钎焊实验,通过扫描电镜和能谱分析仪进行了接头显微组织观察与物相分析,并进行了钎焊接头的高温性能测试.实验结果表明;在保温60min的工艺规范下,界面实现良好的结合,钎缝内部孔洞缺陷最少,钎缝组织均匀致密,有利于钎焊接头性能的提高;在更长的保温时间120min下,界面

采用高温高压及电化学腐蚀实验表征了Q235钢以及表面沉积NiCrAl涂层后Q235钢的耐蚀性能,研究了NiCrAl涂层对提高碳钢耐蚀性的作用.NiCrAl涂层采用等离子喷涂制备,厚度约150μm.结果表明,表面包覆NiCrAl涂层以后Q235钢的腐蚀速率显著降低;高温高压腐蚀实验后NiCrAl涂层表面仍保持喷涂态形貌,未发生明显的腐蚀,而Q235钢表面覆盖一层黑色的FeCO3,且表面出现明显的点蚀
采用连续驱动摩擦焊对X80管线钢进行焊接,分析焊接接头的组织及力学性能.结果表明:X80管线钢连续驱动摩擦焊焊接接头焊缝区组织为铁素体和粒状贝氏体,X80管线钢热影响区的组织由原始的针状铁素体转变为先共析铁素体、针状铁素体及粒状贝氏体.焊接接头的硬度高于母材,其中焊缝区域硬度最高,达到了247.4,其次是热影响区,母材的硬度最低,且在焊缝两侧,硬度值呈对称分布.
