Abstract : This project was designed to provide new information on the effects of ion implantation on surface (adhesion) and subsurface (deformation) effects during unlubricated sliding of metals. The base materials are copper and iron, and the implanted species are also copper and iron. Thus, in some samples there should only be structural changes caused by implantation (e.g., Fe into Fe, Cu into Cu), while in others there will be composition changes as well (e.g., Cu into Fe, Fe into Cu). Copper and iron were chosen because of the considerable amount of literature available for comparison of results from testing of these metals. Also, their hardness values and deformation behavior are different, the OSU group has experience with both metals, and the phenomenon of selective transfer, extensively studied in the former USSR, usually involves both Cu and Fe.
