Abstract
The effect of high-power ion beam (HPIB) of nanosecond duration on the corrosion of polycrystalline magnesium in physiological solution (0.9% NaCl) has been studied. Slowdown of corrosion rate for magnesium samples irradiated with a current density of 150 A/cm2 was found, which is probably related to doping of the surface layer with carbon. It was found that an increase in the number of irradiation pulses leads to an increase in corrosion resistance in physiological solution, which is apparently associated with the achievement of equality of the rates of formation and destruction of the Mg(OH)2 film in the corrosion process. The formation of needle-like structures on beam-irradiated surfaces during corrosion in NaCl solution is observed, which indicates the directional growth of corrosion products.
研究了纳秒强离子束（HPIB）对生理溶液（0.9% NaCl）中多晶镁腐蚀的影响。当电流密度为150 a /cm2时，镁样品的腐蚀速率减慢，这可能与表层碳的掺杂有关。研究发现，辐照脉冲数的增加导致生理溶液中耐腐蚀性的增加，这显然与腐蚀过程中Mg(OH)2膜的形成和破坏速率相等有关。在NaCl溶液中腐蚀时，在光束辐照表面上观察到针状结构的形成，表明腐蚀产物有方向性生长。
期刊介绍：
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques publishes original articles on the topical problems of solid-state physics, materials science, experimental techniques, condensed media, nanostructures, surfaces of thin films, and phase boundaries: geometric and energetical structures of surfaces, the methods of computer simulations; physical and chemical properties and their changes upon radiation and other treatments; the methods of studies of films and surface layers of crystals (XRD, XPS, synchrotron radiation, neutron and electron diffraction, electron microscopic, scanning tunneling microscopic, atomic force microscopic studies, and other methods that provide data on the surfaces and thin films). Articles related to the methods and technics of structure studies are the focus of the journal. The journal accepts manuscripts of regular articles and reviews in English or Russian language from authors of all countries. All manuscripts are peer-reviewed.
