The high entropy alloy metal coatings can be considered as the accident tolerance fuel (ATF) technologies due to their higher surface hardness, better corrosion resistance, especially superior radiation resistance. Physical vapor deposition (PVD) is an ideal technology for preparing high entropy alloy coatings on fuel assembly surface. The coatings synthesized by PVD have compact structure and high interfacial bonding strength without damaging the mechanical properties of substrate. This paper is an overview of PVD high entropy alloy coatings for ATF in recent years. The performance and potential problems of the existing PVD high entropy alloy coatings system are analyzed from the aspects of fuel assemblies’ service condition, coating’s composition design, performance analysis and failure mechanism. It is put forward that the research of PVD high entropy alloy coating for ATF should be carried out from the degradation mechanism analysis of coating under accident condition, structural component design and engineering PVD process technology, so as to obtain a high entropy alloy coating suit for ATF.
