Abstract

A method is proposed to determine uncontrolled areas of aircraft engine parts in penetrant testing, taking into account the specifics of applying developers of different types (all forms according to ISO 3452-3). The main technological factors affecting the testability of surfaces of parts of complex geometry are presented. A method has been experimentally tested, which makes it possible to determine the uncontrolled zones of engine parts in penetrant testing, due to the specifics of applying different forms of developers. It has been established that when carrying out penetrant testing of parts, especially with complex configurations/geometry, the existing technologies for applying developers may not ensure its high-quality application to all controlled surfaces of parts, as was previously assumed based on the results of an expert assessment. It has been experimentally proven that such structural elements of parts as holes are controlled to a depth much less than the diameter.

渗透测试中复杂结构部件可控性的新视角

摘要考虑到不同类型显影剂（ISO 3452-3 规定的所有形式）应用的具体情况，提出了在渗透测试中确定飞机发动机零件非控制区域的方法。介绍了影响复杂几何形状零件表面可测试性的主要技术因素。对一种方法进行了实验测试，该方法可以确定发动机零件在渗透测试中的非控制区，这与使用不同形式显影剂的具体情况有关。实验证明，在对零件，特别是具有复杂结构/几何形状的零件进行渗透测试时，现有的显影剂涂抹技术可能无法确保高质量地涂抹到零件的所有受控表面，而这是之前根据专家评估结果所假设的。实验证明，孔等零件结构元素的控制深度远小于直径。

期刊介绍： Russian Journal of Nondestructive Testing, a translation of Defectoskopiya, is a publication of the Russian Academy of Sciences. This publication offers current Russian research on the theory and technology of nondestructive testing of materials and components. It describes laboratory and industrial investigations of devices and instrumentation and provides reviews of new equipment developed for series manufacture. Articles cover all physical methods of nondestructive testing, including magnetic and electrical; ultrasonic; X-ray and Y-ray; capillary; liquid (color luminescence), and radio (for materials of low conductivity).
