Method for detecting imperfections, leakage paths or pore distribution in units, involves inserting thin resin with contrast unit in imperfection, leakage path or pores in component, where resin is placed in imperfection, leakage path

摘要

The method involves inserting a thin resin with a contrast unit in an imperfection, a leakage path or pores in a component. The resin is hardened and placed in the imperfection, leakage path or pores by a vacuum proof process. The cross sections of a structure are prepared for a microscopic investigation.
