Platinum group metals have high melting points, strong corrosion resistance, stable chemical properties and low oxygen permeability in high temperature oxygen-containing environments. As thermal protective coating materials, they have gained essential applications in the aerospace field and have excellent prospects for application in frontier military fields, such as protecting hot-end components of hypersonic aircraft. This paper reviews the latest research progress of platinum group metal coatings for high temperature oxidation resistance, including coating preparation technology, oxidation failure and alloying modification. Firstly, it outlines the leading preparation technologies of current platinum group metal coatings, while summarising and comparing the advantages and disadvantages of various existing preparation technologies; Secondly, it focuses on analyzing and summarizing the intrinsic properties, failure forms and failure mechanisms of single platinum group metal coatings in high temperature oxygen-containing environments; On this basis, the necessity, main ways and main achievements of alloying modification of platinum group metals are sorted out and pointed out. Finally, the future development of high temperature oxidation resistant platinum group coatings is discussed and prospected.
