Abstract: |
The cold-sprayed deposit is consisted by the stacked particles. The interface strength of between each particle is dominant factor of whole of cold-prayed deposit. Interface characteristic is also important to describe the deposit properties. We carried out micro-scale interface strength test in FIB (Focused Ion Beam) chamber. This system allows fabricating and picking up micro-scale specimen. It is possible to evaluate single particle strength and inter-particle interface strength. Moreover this small specimen was evaluated by SEM-EBSD method. Form the result of EBSD technique. From those evaluations, we can discuss the relationship between strength and character of the interface.
