| Abstract Scope |
Silicon oxycarbonitride (SiOCN) coatings, derived from polysilazane precursors, are prized for their stability, oxidation resistance, and mechanical strength, finding utility in protective coatings. Tailoring their composition and microstructure, achieved through precursor modification and pyrolysis conditions, allows precise control over properties such as stability and mechanical strength, largely influenced by the incorporation of free carbon. The transformation of carbon within SiOCN, from amorphous clusters to graphitic carbon with temperature, impacts mechanical and thermal characteristics. This study delves into how carbon quantity, composition, and structure influence the stability, mechanical properties, and degradation behavior of SiOCN coatings. |
