Medical application of ion implantation (Ionguard TM) for overall improvement of titanium alloys

Abstract

Ion implantation is an emerging technology that allows for selective modification of the surface properties of materials. Properties such as hardness, corrosion resistance, friction and others can be improved without adversely affecting the bulk properties of the material. This paper concentrates on the discussion of the overall improvement of orthopaedic implants by the ion implantation (IONGUARD TM ) process. The unique capabilities, outstanding features and overall potential of the technology are described. Based on the very impressive improvement in wear, corrosion and fatigue resistance, the ion implantation process is expected to become the technology of choice not only for surface treatment of titanium orthopaedic implants but also in other medical applications such as titanium surgical scissors or dental implants. The technology is also expected to have an increasing contribution in a great variety of other applications such as the aerospace field.
