Effect of ion beam mixing on wear and friction of Fe-Ti multilayered structure on AISI 304 stainless steel

Abstract
Dry sliding properties of ion beam mixed multilayered Fe-Ti structures deposited on AISI 304 stainless steel were studied over the composition range 0–100% Ti using samples with a linearly varying composition of constituents. Our measurements revealed that a ductile surface was formed with good sliding properties over the wide composition range by ion beam mixing of deposited layers. These beneficial effects were not obtained on as-deposited samples or by ion bombardment of either a substrate or pure iron layer deposited on a substrate. Thus, it is concluded that both the ion beam processing and composition as well as the resulting microstructure are essential for improved tribology.
