Surface modification of industrial components by ion implantation

Ion implantation is an emerging technology that allows the selective modification of the surface properties of materials. Properties such as hardness, corrosion resistance and friction can be improved without adversely affecting the bulk properties of the material. This paper concentrates on the discussion of the industrial applications of the ion implantation process. The unique capabilities, outstanding features and overall potential of the technology are described. Based on the experiences of Spire Corporation, successful applications of the ion implantation process are presented and the criteria for choosing promising candidates are outlined. The technology is expected to have an increasing contribution in a great variety of applications from aerospace to orthopaedics. (orig.)
