Replenishing the oxidation-induced Al-depletion in Cr2AlC MAX phase coatings

Key Points

The research aims to develop an aluminum reservoir to continuously supply aluminum for Cr2AlC coatings.
Synthesize fine- and coarse-grained aluminum reservoirs to support coatings.
Conduct microstructure and chemical analyses to assess aluminum supply.
Evaluate oxidation resistance of coatings at high temperatures.
Fine-grained aluminum reservoir successfully supplies aluminum, verified by microstructure analyses.
Enhanced oxidation resistance observed in coatings utilizing the fine-grained reservoir.

Abstract

• Proof-of-concept of Al-reservoir for continuous Al supply towards Cr 2 AlC coatings. • Microstructural design allowed synthesizing fine- and coarse-grained reservoirs. • Al supply from fine-grained reservoir shown by microstructure and chemical analyses. • Enhanced oxidation resistance at high temperatures using the fine-grained reservoir.
