Abstract:
The formation of an amorphous layer due to irradiation of intense pulsed ion beams (PIBs) has been studied experimentally. A mixed carbon and fluorine PIB with energy of 180 keV, ion beam current density of 180 A/cm 2 and pulse duration of 30 ns is irradiated on a Ni 65 Cr 15 P 16 B 4 alloy, resulting in the formation of an amorphous layer on the substrate surface to a depth of 0.66 µ m which is consistent with the thermal diffusion length. Repeated irradiations of PIB lead to the formation of an amorphous phase at depths exceeding 0.66 µ m from the surface. PIB irradiation leads to rapid heating of the substrate surface to its boiling point (2732° C), and the cooling rate from the melting point to the glass transition point is estimated to be 2.2×10 9 ° C/s which is larger than the critical cooling rate for amorphous layer formation of nickel alloys.
