先进的多步钎焊（AMSB）先进制造方法已被开发用于制造聚变反应堆中的钨（W）/铜合金偏滤器排热组件。 AMSB的原理是先进钎焊技术（ABT）的重复应用。 ABT 最初是在我们之前的工作中开发的，用于将 W 和氧化物弥散强化铜合金 (ODS-Cu: GlidCop®) 与 BNi-6 (Ni-11% P) 填充材料进行接合。 AMSB的特点是通过应用ABT可以实现GlidCop®(GlidCop®/GlidCop®)与不锈钢(SUS)和GlidCop®(SUS/GlidCop®)的密封连接。因此，AMSB 能够使用适当的盖材料（例如 GlidCop® 或 SUS）来生产防漏密封结构，用于预处理的矩形冷却流路通道。矩形冷却流路通道在散热能力方面具有优势。 AMSB 的另一个特点是 AMSB 接头的物理性能对重复钎焊热循环具有很强的耐受性。因此，重复使用 ABT 不会对 GlidCop®/GlidCop® 和 SUS/GlidCop® 的密封性造成任何不良影响。矩形流体流道、V形交错筋结构的新型AMSB型组件研制成功；其中，预处理的矩形冷却流路通道采用GlidCop®和SUS盖结构密封，具有密封条件。该组件在反应堆相关条件下表现出优异的排热能力，功率约为 30 MW m− 2。
The advanced fabrication method named advanced multi-step brazing (AMSB) has been developed for fabrication of a tungsten (W)/copper alloy divertor heat removal component in a fusion reactor. The principle of AMSB is repetitive application of the advanced brazing technique (ABT). The ABT was originally developed in our previous work for jointing of W and oxide dispersion strengthened copper alloy (ODS-Cu: GlidCop®) with the BNi-6 (Ni-11% P) filler material. The special feature of the AMSB is that the leak-tight joint of GlidCop®(GlidCop®/GlidCop®) and of stainless steel (SUS) and GlidCop®(SUS/GlidCop®) can be realized by application of the ABT. Therefore, the AMSB enables production of a leak-tight sealing structure with the appropriate lid material such as GlidCop® or SUS for a pre-processed rectangle-shaped cooling flow path channel. The rectangle-shaped cooling flow path channel has an advantage regarding its heat removal capability. Another special feature of the AMSB is that the physical properties of the AMSB joint has strong tolerance against the repetitive brazing heat cycle. Thus, repetitive application of the ABT does not cause any undesired effects on the leak tightness of the GlidCop®/GlidCop® and the SUS/GlidCop®. The new AMSB type component with the rectangle-shaped fluid flow path and the V-shaped staggered rib structure were successfully produced; therein a pre-processed rectangle-shaped cooling flow path channel was sealed with a GlidCop® and SUS lid structure with leak-tight conditions. The component showed excellent heat removal capability under reactor-relevant conditions with∼ 30 MW m− 2.
