Porous-monolithic TiNi-based materials are fabricated by sintering TiNi powder on monolithic TiNi plates, followed by their surface modification with a low-energy high-current electron beam. Their corrosion resistance is examined in a biological medium by the method of voltamperometry using linear scanning, and their structural features are studied by the methods of optical profilometry, scanning electron microscopy and X-ray microanalysis. A comparison of the corrosion rates of the porous-monolithic samples is performed, and it is found out that the new composites possess better corrosion resistance compared to that of TiNi plates due to a homogeneous phase composition of the surface. A treatment of the TiNi-based powder alloy with LEHCEB is thought to be effective in optimizing the properties of materials used in implantology.
