项目摘要

The objective of this research is to develop new three-dimensional micro-welding methods being enable to freeform aluminide intermetallics, refractory metals and alloys which are superior in heat, corrosion and wear resistances, but difficult in manufacturing and machining. We aim to establish the remote fabrication process by combining 3DMW and IT technology in future. The obtained results are summarized as follows.1.3D micro-welding which can freeform dense aluminide intermetallics and other refractory metal objects has been first developed in the world.2.It is a CAD/CAM system to form molten micro metal beads by discharging arc to the tip of a thin metal wire with around 200μm in diameter and build up three dimensionally. We have succeeded in formation of Ti, Ni, Ta, TiNi, inconel beads, and their simple 3D objects. The morphology, composition, and microstructure of beads were also investigated.3.It was demonstrated to synthesize and simultaneously freeform intermetallics such as NiAl and TiNi by providing two different wires alternately in 3DMW system.4.We added a function of metal nitride layer formation to 3DMW by producing a micro molten pool at the surface of a metal substrate and blowing nitrogen gas. Furthermore, by moving a discharging electrode and providing a thin aluminum wire to the small molten pool, the aluminide coating was prepared on the metal surface. By these methods, TiN coating on Ti and TiAl, and NbN on Nb were performed. The NbAl_3 layer was formed on Nb as well. These coatings showed remarkable improvements in hardness, wear and oxidation resistances.We could establish the basic technology of freeforming and coating of heat, wear, corrosion resistant objects by this research.

这样做的目的是开发新的三个身分微焊接方法，可以使弗雷米尼德式间的金属和合金在热，折磨和耐磨性方面较高，但在人间效果和加工方面很难。将来获得的3DW和杂志。金属珠的尖端，直径约200μm，我们以ti，ni，ta，tini，inconel珠子的形成率占据了。是通过在3DMW系统中交替提供两条不同的电线，是ALSA自由形式的金属间层间，例如NIAL和TINI。4。我们通过在金属底物的表面上产生微熔池和吹氮气来添加金属氮化金属层形成的功能。通过这些方法向小熔融池表面提供铝电线，在Ti和Tial上提供锡层涂层，并在NB上形成了NBN层上的NBN。 WW可以通过这项研究来建立自由形成和涂层的自由形成和涂层的基本技术。
