Use of Radioactive Beams of 7Be Nuclei to Study the Wear Resistance of Materials

Аннотация

This work is devoted to the use of beams of radioactive nuclei for applied purposes – to study the wearresistance of materials used in different industries. The crux of the method is that the radioactive nuclei obtained in the nuclear reactions ¹H(⁷Li, ⁷Be) and ¹H(¹⁰B, ⁷Be) are implanted in the experimental sample. After implantation of the nuclei, the sample undergoes wear tests. The γ-radiation of the implanted nuclei is high-energy; the spectrum is comparatively simple and does not produce appreciable radiation damage in the test samples. The method has been successfully tested in determining the wear-resistance of machine parts and mechanisms.
