Refractory Ion-Implanted Materials Modified Radioactively


Ion-implantation is widely applicable in industry for modification of physical-mechanical, chemical and other properties of surface materials. Details, items, machine tools, various devices based on those metals with rather high working capacity, applicable in many fields of production preserving common design and technology of their manufacturing. In many world countries ion-implantation service centers are working for various branches of industry.

Despite the progress many important resources of ion-implantation have not been fully exhausted, corresponding materials and their realizations are limited.

Wide-scale production of various application items for mass consumption will be of great economic profit being strong motivation for further researches.

Our project comprises development of: tungsten, molybdenum, niobium, pilot sample refractory materials of new class with radically improved mechanical, frictional, emission, adsorptive (surface-energy) properties via high-fluence ion-implantation. This work is proper continuation of the years’ experience by SIPT in the field of ion-implantation.

Innovative Aspect and Main Advantages

  • Development technology processes via high-fluence ion implantation of niobium, molybdenum, tungsten and titan.
  • Creation pilot sample ion-implanted niobium, molybdenum, tungsten with precision-controlled radically improved mechanical, friction, emission and adsorption properties preserving at the time plastic properties of the rest shape, sizes and quality of he surface and virgin samples.

Areas of Application

Practical value implies expansion of high-mechanical ion-implanted metals class including their sphere of application promising great economic effect in refining, automobile, machine- building, chemical, medical and in other fields of production.

  • Determination regularities and mechanisms of structural- phase conditions; correspondingly macroscopic properties of refractory metals ion-implanted by ions of: boron, nitrogen, carbon, oxygen, silicium and argon.
  • Overall description of structural-phase transformation mechanisms, increasing micro-hardness, wear-resistance and emission-adsorptive parameters of the transition materials at ion-implantation.

Stage of Development

Laboratory tested.

Actuality is conditioned by scientific validation of forecasting problems tending to improve parameters of ion-implanted metals and to degradation of macroscopic parameters of the materials in nuclear and thermal nuclear reactors.
