Coating-Substrate Interface Stress Management in Wear Protection of Light Alloy Components

Source

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.
