Modifying the composition of a brass and bronze surface layer under a high power ion beam of a nanosecond duration

Formation of Microcrystals on a Surface of Commercial Chlorinated Polyvinyl Chloride under the Action of a High-Power Ion Beam of Nanosecond Duration

“…The reverse deposition of ablation products can lead to the formation of conical structures on the surface during multiple-pulse laser irradiation of poly­(ether sulfone) films . Under HPIB action on brass, we also observed the reverse deposition of zinc (the most volatile component of this alloy, which has a high saturated vapor pressure) on the brass surface . Therefore, we assume that the growth of microcrystals occurs through the reverse deposition of CPVC ablation products.…”

“…15 Under HPIB action on brass, we also observed the reverse deposition of zinc (the most volatile component of this alloy, which has a high saturated vapor pressure) on the brass surface. 16 Therefore, we assume that the growth of microcrystals occurs through the reverse deposition of CPVC ablation products. The nuclei for the growth of microcrystals can be nanoparticles or large polymer fragments that are formed during ablation and then deposited on the irradiated surface.…”
