Outline of Final Research Achievements

The aim of study is to improve the performance of metal wire which is indispensable to cut ingots such as Si, SiC as a wafer, by composing high-strength carbon onion particles to a metal (Ni) wire surface. As a result of implantation of carbon ions into the surface of Ni wire by use of plasma based ion implantation and deposition technique, carbon nanoparticles approximately 50nm in diameter on the surface of Ni wire were observed by a scanning electron microscopy. In addition, from the analysis of Raman spectroscopy, the nanoparticles which are synthesized on the surface of Ni wire have the structure of the carbon onion particle. Based on this study, it is expected to develop a new-type metal wire with high performance and durability. Also, it is expected to reduce the loss of ingot materials when cutting.
