“…The results obtained from ablation tests provide insight into the high temperature performance of REO‐modified coatings. During ablation tests of Sm 2 O 3 doped ZrB 2 ‐SiC coatings, the formation of an in situ dense cubic ZrO 2 scale stabilized by Sm 2 O 3 was observed 51,74,75 . As mentioned earlier, this in situ Sm 2 O 3 ‐ZrO 2 scale might be beneficial in enhancing the radiative characteristics of UHTC materials as this scale helped lower the surface temperature of the samples during ablation testing.…”

In addition, this scale survives possibly up to any temperature between 2200 and 2600 • C before it transforms into liquid as determined by the phase boundaries of Sm 2 O 3 -ZrO 2 solid solution.…”

Emissivity as a function of wavelength, direction, and temperature correlates to a material's efficiency in radiating thermal energy. Knowledge of emissivity is essential for designing and developing radiation-cooled thermal protective systems for hypersonic applications. It is desirable to achieve a high emissivity (with a value close to 1) to maximize heat radiation from a hot surface of a hypersonic vehicle's leading edge during atmospheric re-entry. With the goal of providing the hypersonic materials community with this necessary knowledge, this article offers a basic understanding of thermal radiation, methods for measuring emissivity at high temperatures, and a comprehensive overview of the emissivity of ultra-high temperature ceramics.

Robotic manipulators play an innovative role as a new method for high-precision, large-scale manufacturing of composite components. However, machining composite materials with these systems presents unique challenges. Unlike traditional monolithic materials, composites exhibit complex behaviour and inconsistent results during machining. Additionally, robotic manipulator as a machine tool often associates with stiffness and vibration issues which adds another layer of complexity to this approach. By employing a comprehensive analysis and a combination of quantitative and qualitative review methodology, this review paper aims to survey diverse properties of composite materials by different categories and their interaction with machining processes. Subsequently, a survey of manufacturing techniques for composite machining following with a review in various modeling practices to capture material machining behaviour under a systematic framework is presented. Thereafter, the reviewed literature examines the errors inherent in robotic systems, alongside ongoing research efforts in modeling to characterise robot behaviour and enhance its performance. Afterward, the paper explores the application of data-driven modelling methods, with a primary focus on digital twins, in enabling real-time monitoring and process optimisation. Finally, this paper aims to identify the gap in this field and suggests the potential routes for future research and application as well as their challenges.
