A research group led by Associate Professor Kazuhiro Ogawa at Fracture
and Reliability Research Institute, Tohoku University has developed an
innovative repair/coating technology that is applicable when a surface
temperature is more than 900 degrees C. This technique is based on a
particle adhesion technology called cold spray. The research has been
conducted as a part of Industrial Science and Research and Development
Project by New Energy and Industrial Technology Development Organization
(NEDO).

 The research group has successfully developed extremely dense films on
heat-resistant Ni-base superalloy substrates. Computational science has
helped to optimize spray condition for metallic particles. The new
technology can be used for not only metallic materials but also the
other materials. This new technology is expected to be applied to
devices and structures in various environments.
