We investigate the optimization of maintenance methodology using sensing technology, material evaluation technology, etc. for large-scale complicated systems, such as an energy plant.:

1.Development of non-destructive evaluation technique and health monitoring method of structures.
2.Development of the non-destructive evaluation technique of structure material.
3.Understanding of the functionality and application to energy-saving of a hard carbon coating materials.

Development of non-destructive evaluation technique and health monitoring method of structures.
          

We investigate about the maintenance and energy saving using sensing and material evaluation technique for large-scale complicated systems, such as an energy plant. We evaluate and monitor the condition of structural components of Electric Power Plants using advanced electromagnetic nondestructive evaluation (ENDE) techniques.

Development of the non-destructive evaluation technique of structure material

We propose lifecycle evaluation of materials from pre-service to aging degradation. Our activities includes nondestructive evaluations of matrices for various cast irons, susceptibility to stress corrosion crackings, degradation prior to creep damage. In addition, we propose EMAT-EC dual probe that combines the advantages carried by ultrasonic testing and eddy current testing, aiming at application to monitoring of flow assisted damages.

Understanding of the functionality and application to energy-saving of a hard carbon coating materials.

Highly efficient mechanical systems are necessary for saving resources and energy. Especially, in order to get the high reliability and durability requested for the high-performance mechanical system, it is necessary to control “contact” with a high degree of accuracy. We are investigating the nano-micro scale “contact” of the carbon based coatings (Diamond and Diamond-like Carbon which have a character of low friction and low wear) from the viewpoint of flow dynamics.
