The long‐term cyclic oxidation behavior of a single MoSi 2 coating, 10%, and 50% Ti 3 SiC /MoSi composite coatings on Nb–Si‐based alloys is systematically investigated. thermal gravimetric analysis reveal that the coating initially exhibits stable mass change (–3.7 mg cm −2 ) for ≈37 cycles, followed by rapid increase in gain (2.2 after 100 cycles). demonstrated linear kinetics with 3.5 cycles. Notably, 10% showed superior stability, minimal (–2.7 over scale formed characterized as compact, dense, firmly adhered to substrate, primarily consisting an amorphous SiO matrix interspersed fine TiO grains. After cycles oxidation, both exhibited significant degradation damage at edges.

This paper presents a detailed characterization of the microstructure and high-temperature oxidation behaviour MoSi2 coatings obtained by pack cementation methods on Mo-based substrate. The author focused challenges applying combustion chambers in rocket engines. Due to these assumptions, resistance was analyzed temperature range 1200–1700 °C. A particular area interest surface condition after tests, characterized their roughness. presented studies showed very beneficial oxidized from point view both protective coating's morphology durability under conditions roughness responsible for gas flow stability actual working conditions. identified microstructural phenomena related MoSi2-based coating formation, its thermal interaction were described thermodynamic view. Those analyses revealed that thermodynamically most stable silicide compound during first stage formation is Mo5Si3, not MoSi2. It suggests between Si-rich atmosphere Mo5Si3 layer determines growth progress coating. necessary further an excess active silicon sources reactive process.
