This study proposes an innovative technique for repairing of cracked or damaged parts of structures, such as nuclear or thermal power plants, by means of cold gas dynamic spray (CS) technique. In the case of generation of cracks etc, in the structure, the cracks can be repaired by welding. However, the welding spends considerable time on repair, and also needs special skills. The CS techni que is known as a new technique not only for coatings but also for thick depositions. It has many advantages, i.e. ...

Fundamental Study on Repairing Technique for Cracked or Damaged Parts of Structuresby Cold Gas Dynamic Spray Technique

The remote operated vibrating sample magnetometer (VSM) for neutron irradiated samples has been developed. The maximum range of applied magnetic field is more than ±0.5/?0 A/m, and the resolution of magnetic moment is higher than 5 ×10-8 A?m2. The hysteresis loops of neutron irradiated samples were measured by this VSM, and the relationships between dose, which is one of epresentative irradiation parameter, and magnetic properties such as magnetic coercive force were examined. As result, it was revealed tha...
