STATUS OF EXPERIMENTS ON SURFACE MODIFICATION OF MATERIALS ON THE ACCELERATOR HIP-1

Ion implantation is an effective method for materials surface modification for various technological applications. The most common examples of its use are an increase of the durability, corrosion resistance, heat resistance for various industrial steels and special alloys for applications in biology and medicine, strengthening and changes in the morphology of the surface layers of polymers. Work in this direction is underway at the accelerator HIP-1 in ITEP. To provide the experiments, the beams of iron, vanadium and titanium generated by vacuum-arc metal ion source, as well as ion beams of nitrogen generated by duoplasmatron ion source are used. Several sets of experiments for the modification of the surface features were carried out. The transmission electron microscopy (TEM) and tomographic atom-probe microscopy (TAP) were used for samples analysis after ion beam treatment.
