“…High-temperature alloys are widely used in aircraft engines owing to their excellent high-temperature strength, thermal fatigue performance, corrosion resistance and creep resistance. They generally account for approximately 50% of the weight of aircraft engines (Rathi et al, 2023). Figures 3 and 4 illustrates the application of superalloys in turbine engines.…”

PurposeUnconventional machining processes, particularly ultrasonic vibration cutting (UVC), can overcome such technical bottlenecks. However, the precise mechanism through which UVC affects the in-service functional performance of advanced aerospace materials remains obscure. This limits their industrial application and requires a deeper understanding.Design/methodology/approachThe surface integrity and in-service functional performance of advanced aerospace materials are important guarantees for safety and stability in the aerospace industry. For advanced aerospace materials, which are difficult-to-machine, conventional machining processes cannot meet the requirements of high in-service functional performance owing to rapid tool wear, low processing efficiency and high cutting forces and temperatures in the cutting area during machining.FindingsTo address this literature gap, this study is focused on the quantitative evaluation of the in-service functional performance (fatigue performance, wear resistance and corrosion resistance) of advanced aerospace materials. First, the characteristics and usage background of advanced aerospace materials are elaborated in detail. Second, the improved effect of UVC on in-service functional performance is summarized. We have also explored the unique advantages of UVC during the processing of advanced aerospace materials. Finally, in response to some of the limitations of UVC, future development directions are proposed, including improvements in ultrasound systems, upgrades in ultrasound processing objects and theoretical breakthroughs in in-service functional performance.Originality/valueThis study provides insights into the optimization of machining processes to improve the in-service functional performance of advanced aviation materials, particularly the use of UVC and its unique process advantages.

“…High-quality nanometric finish surfacing is one of the significant challenges when machining INVAR-36 ® since it has low hardness and high chemical activity [44,57]. Hauschwitz et al [58] suggest that optimizing the rolling torque, polishing speed, and reducing the polishing depth can improve the process's efficiency and quality while lowering subsurface damage [59,60]. Moreover, some authors have been overcoming these issues thanks to the brisk development of the selective laser melting (SLM) process [61][62][63] allied to a post-machining process.…”

Injection moulds are crucial to produce plastic and lightweight metal components. One primary associated challenge is that these may suffer from different types of failures, such as wear and/or cracking, due to the extreme temperatures (T), thermal cycles, and pressures involved in the production process. According to the intended geometry and respective needs, mould manufacturing can be performed with conventional or non-conventional processes. This work focuses on three foremost alloys: AMPCO® (CuBe alloy), INVAR-36® (Fe-Ni alloys, Fe-Ni36), and heat-treated (HT) steels. An insight into the manufacturing processes’ limitations of these kinds of materials will be made, and solutions for more effective machining will be presented by reviewing other published works from the last decade. The main objective is to provide a concise and comprehensive review of the most recent investigations of these alloys’ manufacturing processes and present the machinability challenges from other authors, discovering the prospects for future work and contributing to the endeavours of the injection mould industry. This review highlighted the imperative for more extensive research and development in targeted domains.

“…The phenomenon known as galvanic corrosion occurs when two metals with different compositions come into electrical contact and are submerged in an electrolytic solution, such as seawater [19]. Metals with higher reactivity have a more pronounced tendency to undergo corrosion at an accelerated rate, whilst metals with lower reactivity demonstrate a comparatively little susceptibility to such chemical deterioration.…”

This study explores the forefront of super alloy coatings, examining their significant role in minimising the adverse effects of corrosive and oxidative processes on materials working in harsh conditions. This study highlights the transformative potential of super alloy coatings in extending the lifespan and enhancing the reliability of critical components. It achieves this by presenting a comprehensive overview of the fundamental principles, fabrication methodologies, and practical applications associated with these coatings. As many sectors navigate more difficult environments, the effective incorporation of advanced coatings presents a potential direction, advancing the field of materials science and guaranteeing consistent performance in the presence of significant challenges. The emergence of super alloy coatings represents a significant transformation in the field of corrosion and oxidation control, providing a robust defence against the persistent deteriorating factors seen in highly challenging settings. The combination of complex production procedures and superior material qualities empowers these coatings to strengthen materials, therefore assuring their durability.
