Abstract
Metal systems based on aluminum and copper coated with nickel irradiated by a high-power ion beam of nanosecond duration have been studied by scanning electron microscopy and local X-ray microanalysis. Dispersed particles of micro- and nanosizes have been found on the surface target. Their composition and formation mechanism differ. It has been shown that microparticles were formed during mixing of film and target atoms and consisted of corresponding components. Nanoparticles were mainly composed of the coating material, and their formation was associated with the dispersion of the Ni film due to the presence of a thin oxide layer on the sample surface. The deposition of Ni ablated by a high-power ion beam can affect the formation of nanoparticles.
