316L stainless steel (316L SS) and NiTi alloy are the two metallic materials widely used in the biomedical fields. However, as medical implant instrument materials, they will release harmful metal ions after the implantation and its corrosion product will affect the normal physiological functions of the human body. In the present study, the high current pulsed electron beam (HCPEB) technique was employed to modify the surface of 316LSS and NiTi alloy with the aim of improving the corrosion resistance of the...
