Abstract:

Microencapsulated fluorescent dye pentrant materials were evaluated for feasibility as a technique to detect cracks on metal surfaces when applied as a free flowing dry powder. Various flourescent dye solutions in addition to a commercial penetrant Zyglo ZL-30 were microencapsulated and tested on nondestructive inspection crack standards. The material could be applied dry with standard spray apparatus, and removed by blowing air, vacuum or with a detergent water mixture. Indications of cracks 0.5 microns in width or larger could be visually observed in the tests conducted to date. Author
