Ion Beam Modification of Metals: Mechanical Properties and Structure
Abstract
The objective of this work was to study the phase transformations and property changes of metals bought about by ion beam induced materials modification and then to use this information to produce stable surface layers exhibiting optimal chemical and mechanical integrity. Summary of Most significant Results: 1) Amorphous alloys can be formed by ion mixing a wide variety of metal systems within defined regions of atomic composition. 2) Two step processing such as implanting Carbon and Nitrogen into ion beam mixed layers improves the friction behavior. 3) Iron-Titanium mixed on stainless steel and implanted with N and C results in a wear resistant layer that deforms to depths greater than the thickness of the modified layer. 4) These novel structures on stainless steel were used to demonstrate a technique for distinguishing between deformation and material removal on worn surfaces. 5) Mixing substantial amounts of gold into Ti improves corrosion resistance of the Ti without appreciably degrading the wear and friction behavior.
