Оценка вероятности выявления эксплуатационных дефектов в деталях авиационной техники из жаропрочных сплавов с использованием дефектоскопических жидкостей отечественного и зарубежного производства

Work was carried out to evaluate the effectiveness of the identification of operational defects during capillary testing of parts of aircraft from heat-resistant alloys using flaw detection fluids of domestic and foreign production, revealing defects with an opening size of 1 μm or less. Two complementary approaches to a qualitative assessment of the effectiveness of various sets of flaw detection materials recommended for use in conducting capillary control in the production and operation of parts of aircraft equipment are considered with the aim of choosing a kit that identifies defects of a certain type with the smallest dimensions. The first approach is based on the assessment of the main defectoscopic properties of penetrating multicomponent liquids, which ensure their penetration into the cavities of surface defects, and the second is based on the experimental determination of defect detection parameters with a probability of 50 and 90 % with a confidence probability of 50 % and with a probability of 90 % with a confidence probability of 95 %.
