Degradation of Aluminide coatings on Platinum-containing model and real superalloys – ALUPLAT

Submission summary

New Pt-containing nickel-based superalloys are currently under study to increase their mechanical resistance at high temperatures. Their environmental resistance should also be better. However, the Pt content in these alloys appears insufficient (Pt is expensive) and the influence of the remaining alloying elements is unknown, let alone in the new “biofuel” environments. This project gathers experts in the mechanics, corrosion, surface treatment and in situ characterization of superalloys to investigate the onset of degradation (chemical, mechanical and coupled). This settles the basis to study the impact of a coating (Al/Si/rare earth) on such degradation. The degradation at the gas/alloy and coating/alloy interfaces will be studied in model and real alloys under hot corrosion, oxidizing and fatigue conditions, which is quite original for these brand new Pt-containing superalloys. The impact on Science, Society and on the turbine industry could be thus impressive.
