Formation of Nanodimensional Layer of Catalytically Active Metals on Stainless Steel Surface by Ionic Implantation

It was shown by XRD, thin-layer XRD, SEM, and XPS that ionic implantation of Mo, Ni, and Ti on the surface of stainless steel (SS) leads to the formation of a layer of implants 80-100 nm thick on the SS surface with partial penetration of the implant in the surface layer to a depth of 20-50 nm. It was found that the mechanical properties and thermal stability of the composites depend on the presence of such a subsurface layer. The possibility of using the composites in catalysis and photocatalysis is discussed.
