用于生产耐高温复合主体的工艺
摘要：
本发明涉及一种用于生产耐高温复合主体(2)的工艺，方法是在一个区域上将第一非金属部分(10)经由粘合焊料层(12)接合到由Mo、基于Mo的合金、W或基于W的合金组成的第二金属部分(6)。此处，由所述第一部分(10)、第一Zr焊料和中间层组成的第一布置是首先在第一焊接步骤中焊接在一起的。得到的部分复合主体的第二布置、邻接所述中间层和所述第二部分(6)的第二焊料随后在第二焊接步骤中焊接在一起。所述中间层是由元素Ta、Nb和/或W中的至少一个以至少90原子％的程度形成的。所述第二焊料是精确地由Ti、基于Ti的焊料组合、基于V的焊料组合、Zr或基于Zr的焊料组合组成的组中的一种材料形成的并且经选择使得它在与所述第二布置中的所述第一Zr焊料相比的较低温度下熔化。
摘要（英）：

The present invention relates to a process for producing a high-temperature-resistant composite body (2) by joining an area of a first, nonmetallic section (10) via a bonding solder layer (12) to a second, metallic section (6) composed of Mo, a Mo-based alloy, W or a W-based alloy. Here, a first arrangement composed of the first section (10), a first Zr solder and an intermediate layer is firstly soldered together in a first soldering step. A second arrangement composed of the resulting part composite body, a second solder adjoining the intermediate layer and the second section (6) is subsequently soldered together in a second soldering step. The intermediate layer is formed here to an extent of at least 90 atom% from at least one of the elements Ta, Nb and/or W. The second solder is formed by precisely one material from the group consisting of Ti, Ti-based solder combination, V-based solder combination, Zr or Zr-based solder combination and is selected such that it melts at a lower temperature than the first Zr solder in the second arrangement.
