| Research Abstract |
In order to establish a fundamental of cold spray technology, which is recognized to be a novel high-speed thick coating or bulk formation technology by depositing non-melt solid powder particles, advancement of the process by optimizing process parameters and verification of bonding mechanism at interface between particles and solid substrate were conducted. As a result, existence of practical deposition windows by using normal air or nitrogen as a working gas and distribution in adhesive character at interface between particle and substrate according to particle's radius were experimentally verified. By summarizing the results obtained, the possibility in advancement of cold spray technology and establishment of fundamental of the process were clarified in the present study.
