    Abstract

    Hard coating light alloys for wear protection presents an interface stress problem due to mismatch in elastic constants across the film-substrate interface. The displacement formulation method is used in this work to calculate interface stresses as a function of contact parameters, coating/substrate properties, and coating thickness. Quantitative results obtained suggests that interface stresses can be managed with a judicious choice of coating materials, film thickness, contact parameters, and film deposition conditions.
