Research progress on the preparation and oxidation behavior of Ti2AlC(CxNy)MAX phase and its application in high-temperature absorbing coatings
摘要
Abstract
Ternary layered compounds(MAX)phases have attracted extensive attention in the fields of spacecraft component protection,surface modification of space electronic devices,and advanced materials for extreme environments due to their unique layered crystal structures and the combination of ceramic and metallic properties.Among them,Ti2AlC and Ti2AlN,as representative 211-type MAX phases in the Ti-Al-X(X=C,N)system,exhibit low density,excellent thermal and electrical conductivity,high-temperature stability,oxidation resistance,and good machinability,making them promising candidates for advanced space protection materials.This review summarizes recent progress in the preparation,structural regulation,and performance optimization of Ti2AlC,Ti2AlN,and their Ti2Al(C,N)solid solutions.Firstly,the effects of different synthesis routes on the formation process and phase composition of MAX phase materials are reviewed.The influence of reactant composition,sintering temperature,pressure conditions,and reaction pathways on impurity phase formation and phase purity is discussed in detail.Key factors for obtaining high-purity single-phase Ti2AlC and Ti2AlN materials through precise control of reaction mechanisms are summarized.Secondly,recent advances in the mechanical properties of Ti-Al-C,Ti-Al-N,and Ti-Al-C-N system materials are systematically reviewed,with emphasis on the effects of grain size,defect structure,and C/N substitution on hardness,elastic modulus,and strengthening mechanisms.The results indicate that C/N solid solution at the X sites can effectively regulate lattice distortion and local bonding environments,thereby improving the comprehensive mechanical properties of MAX phase materials.Furthermore,the high-temperature oxidation behavior and protective mechanisms of Ti2AlC and Ti2AlN are discussed.Particular attention is paid to the selective oxidation of Al atoms and the formation of dense Al2O3 protective layers,as well as the effects of grain size,oxide scale structure,and elemental diffusion on oxidation resistance.In addition,the interfacial bonding behavior between MAX phases and heterogeneous materials is reviewed,highlighting their potential applications in protective coatings and composite structures for aerospace environments.Finally,future research directions for Ti2AlC,Ti2AlN,and related solid solutions are proposed,providing theoretical guidance and design strategies for the development of lightweight,high-performance MAX phase materials for extreme space environments.关键词
