| Summary: | Title screen It is shown for the first time that the energy impact of a repetitively-pulsed titanium ion beam at a pulse duration of 450 μs and a power density from 50 to 100 kW/cm2 on the surface of AISI 420 steel changes its morphology and performance properties. It is established that the energy impact significantly improves the sample wear resistance. The maximum value of power density is achieved in the case where the sample is heated to 900°C and, given a pulsed increase in the temperature, a repetitively-pulsed melting of the surface may occur. In this case, the wear resistance was observed to increase by a factor of 49 compared to the initial sample. The same irradiation mode significantly improved the modified layer microhardness. It increased to 7.5 GPa, which is 3 times higher than the initial sample parameter Текстовый файл AM_Agreement |
