Abstract
FIELD: flaw detection techniques. SUBSTANCE: developer consists of adsorbent (5-20% by mass) and carrier. The adsorbent has the following composition, % by mass: zeolite NaX 5-20, zeolite NaA 2-20, kaoline - balance. The carrier has the following composition, % by volume: perfluorodecalin - 2-20, freon-113 - balance. When using various penetrants the proposed developer allows detection of defects down to 1 micron in size. EFFECT: higher sensitivity of techniques and fire safety.
