CERTAIN POSSIBILITIES OF USING IRRADIATION FOR SURFACE HARDENING OF METALS (NEKOTORYE VOZMOZHNOSTI ISPOLZOVANIYA OBLUCHENIYA DLYA POVERKHNOSTNOGO UPROCHNENIYA METALLOV),
Abstract
The thermal effect of nuclear irradiation on surface layers of metals was investigated after electronic, ionic, and deuteron irradiation. The equipment consisted of a voltage-pulse generator, electron gun, and a vacuum unit. Considerable increase in the wear resistance of metals resulted from the leveling of microirregularities, fusion of microcracks, and sudden quenching of the surface layer. In a 2nd test, ionic irradiation was achieved in a unit for the electromagnetic sepn. of isotopes by irradiation with Ti ions. The Ti diffused into the surface of the specimens to a depth of 110 microns and wear resistance increased by as much as 20 times compared to the initial resistance. Microhardness increased by as much as 1.5 times. Deuteron irradiation was performed in a cyclotron and resulted in an increase of microhardness by a factor of 2-3, and of wear resistance by a factor of 2-2.5. (Author)
