Аннотация

The methods of positron annihilation, x-ray diffraction analysis, mass spectrometry of secondary ions, Auger electron spectrometry, and metallographic examination were used to study the structures of R6M5 high-speed tool steel, T14K8 hard alloy, and KNT16, TN-20 tungsten-free alloys irradiated with supercurrent carbon ion beams. A modified layer with a complex structure 50-100 mu m thick forms on the surface of the examined specimens irradiated with the powerful ion beam. All the structural changes taking place in the layer improve the service characteristics of the alloys: microhardness increases 1. 5-2 times and durability in machining increases 2. 2-3. 5 times in comparison with the initial reference specimens.
