Abstract

Research has been carried out to assess the defectoscopic properties of various compositions of powder preparations in order to determine whether they can be used as part of a modern Russian set of defectoscopic materials for luminescent penetrant testing that ensures detection of discontinuities with sensitivity class 1 as per GOST (State Standard) 18442. To improve the efficiency and reliability of flaw detection in hard-to-reach places of complex shaped parts, compositions have been selected that increase the brightness, contrast, and stability of the indication pattern to mechanical action due to high rates of adsorptive and adhesive interactions of the used penetrant fluid and the surface of the tested part.
