| 摘 要： | Friction and wear properties of nitrogen-implanted GCrI5 bearing steel and 40Cr structuralsteel were studied under different implantation conditions. It is found that physical and mechani-cal properties, as well as chemical properties of the surface layer are greatly changed by ionirradiation, such as the decrease of surface roughness, the increase of hardness accompanied withthe occurrence of compressive stress, etc.. The results of SEM and Ferro-spectroscopy show thatthese variations in surface properties closely associated with changes in the microstructure causegreat variations in friction and wear conditions, and mechanisms between implanted andunimplanted specimens. Changes in the surface microstructure with iron implantation were identi-fied by Auger electron spectroscopy, transmission electron microscopy and X-ray photoelectronspectroscopy. By means of the orthogonal experiment method, test results for each differentimplantation condition and original hardness of the materials under the same wear test conditionwere comprehensively analysed and discussed.

It is found that physical and mechani- cal properties, as well as chemical properties of the surface layer are greatly changed by ion irradiation, such as the decrease of surface roughness, the increase of hardness accompanied with the occurrence of compressive stress, etc.. The results of SEM and Ferro-spectroscopy show that these variations in surface properties closely associated with changes in the microstructure cause great variations in friction and wear conditions, and mechanisms between implanted and unimplanted specimens. Changes in the surface microstructure with iron implantation were identi- fied by Auger electron spectroscopy, transmission electron microscopy and X-ray photoelectron spectroscopy. By means of the orthogonal experiment method, test results for each different implantation condition and original hardness of the materials under the same wear test condition were comprehensively analysed and discussed. |
