Alteration of Surface Properties by Ion Implantation
Some exploratory experiments involving the bombardment of semiconductor materials by high-energy ions to alter the electrical properties of these materials were conducted in the 1950s. Since then, ion implantation has become a standard processing technique in the semiconductor industry to introduce dopants into a wide range of materials. During the 1970s interest in this technique was extended to modification of the chemical or mechanical properties of metals and the optical and electrical properties of insulators. Reference 1 contains a set of reviews covering studies outside of semiconductor technology. This paper describes studies to extend the use of ion implantation techniques to modify the mechanical properties of structural ceramics.
