Several applications, where extreme conditions occur, require the use of alloys often containing many critical elements. Due to the ever increasing prices of critical raw materials (CRMs)
linked to their high supply risk, and because of their fundamental and large utilization in high tech
products and applications, it is extremely important to find viable solutions to save CRMs usage.
Apart from increasing processes’ efficiency, substitution, and recycling, one of the alternatives to
preserve an alloy and increase its operating lifetime, thus saving the CRMs needed for its manufacturing, is to protect it by a suitable coating or a surface treatment. This review presents the most recent
trends in coatings for application in high temperature alloys for aerospace engines. CRMs’ current
and future saving scenarios in the alloys and coatings for the aerospace engine are also discussed.
The overarching aim of this paper is to raise awareness on the CRMs issue related to the alloys and
coating for aerospace, suggesting some mitigation measures without having the ambition nor to give
a complete overview of the topic nor a turnkey solution.
