摘要：
Low energy high current pulsed electron beam (LEHCPEB) is a fairly new technique for surface modifications. The pulsed electron irradiation induces (i) very rapid heating, melting,solidification and cooling of the surface together with (ii) the formation of thermal stress waves. As a result, improved surface properties of the material, often unattainable with conventional surface treatment techniques, can be obtained fairly easily. This is particularly true for corrosion and tribological properties. In the present work, LEHCPEB was applied on a bio-metallic AISI 3161, stainless steel. It was demonstrated that the in vitro corrosion resistance of the steel can be significantly improved after the LEHCPEB treatment. The improvement in properties can be attributed to the microstructure and chemical modifications in surface layers induced by LEHCPEB.
