- Increasing operating temperatures in aero engines leads to increased engine efficiency. However, at elevated temperature, the titanium alloys used to manufacture many engine components require an oxidation resistant coating that can resist spalling and protect the underlying substrate. This work demonstrates how a bilayer nitride coating can exhibit adaptive conformability via mechanical twinning, thereby accommodating the thermal mismatch strain between the coating and substrate. The innovative interface strengthening design via interdiffusion and inter-reaction provides enhanced protection after extensive thermal cycling.
