R&D outcome and application examples utilizing SPS:
Spark Plasma Sintering (SPS) technologies are being rapidly permeated into institutes and industries these days. Not only universities or industries in Japan, those in overseas countries are interested in SPS effect. The major interest which many industries are showing is if it is applicable not only to R&D in their laboratories but also to actual production processes. As the matter of fact, numbers of SPS applications are being promoted in electric, automotive, electronic, dies & molds, cutting tools, bio-energy, aerospace and other industries.
