Abstract
The vacuum intensification of the process of filling defects in stainless steel and glass samples with penetrants under liquid-penetrant testing has been studied experimentally. Results indicate a high efficiency of vacuum impregnation with small amounts of penetrants on tested surfaces, especially when detecting flaws with openings of 1–3 μm. It has been established that the sensitivity of testing is increased by 30–100% compared with the traditional technique.
