Selective Corrosion Test
Evaluation of mechanical characteristics with selective leaching experiments and measurements of valve materials and laid piping materials for the system to supply firewater in a nuclear power plant.
Description
Selective leaching test
- Deduction of selective leaching conditions by brass, gray cast iron, Al-bronze, and Cu-Ni alloy.
- Deduction of accelerated test conditions (temp., time).
Test and analysis
- Visual inspection
- Hardness
- SEM/EDS
- Tensile strength
