The art of laser ablation in aeroengine: The crown jewel of modern industry

Abstract

In this perspective, laser interaction with materials and its applications in precision engineering are mainly introduced for the manufacturing, as well as maintenance, repair, and overhaul (MRO) of aeroengines. In precision engineering, the laser ablation tool has also been more applicable considering its great advantages in microprocessing and nanofabrication. It is interesting to explore the specific process and characteristics of laser ablation, which play an important role in advanced manufacturing. Due to the complicated production procedures of an aeroengine, it is important to explore the physics behind laser interaction with aerospace and aeronautical metallic materials in order to properly utilize the unique characteristics of lasers, such as high monochromaticity, high brightness, high directivity, and high coherence. Meanwhile, it is beneficial to study the dynamic process of interactions and its mechanisms in laser applications, such as laser cleaning, texturing, and shock peening. There exist both photo-chemical and photo-thermal processes when lasers and materials interact. Several typical cases are introduced, which have great potential and high impact applications in the manufacturing and MRO industry of aeroengines. Based on laser ablation in specific industries, the building-up of MRO support system for aeroengines could be provided by a dynamic mechanism between the pioneering research results and industrial demand, leading to the fast development of advanced high-end manufacturing equipment.

Synthesis Characterization and Applications of Nanoparticles in Environmental Detoxification

“…In addition, the use of the laser-ablation method has not been promoted for industrial usage, mainly because of low production from the physical method. As a result, for the time being, this procedure is not the most cost-effective (Zhou et al, 2020;Ummer et al, 2023). So, the physicochemical methods are nonenvironmentally friendly and costly because combustible, harmful, and toxic chemicals are used which may pose a risk to the environment and they also require high energy for their operations (Ullah et al, 2024).…”

Research on the development strategy of art industry based on RNN model

“…Some developed cities in China, such as Beijing or Shanghai, have already started to set up relevant industrial bases internally, which can give digital media a broader space for development [3][4]. At the same time, China will continue to increase the research and development of relevant technologies, develop more high-end software products, and actively improve the service industry based on the application of information technology [5]. In this way, information technology will be able to promote the development of the digital media industry more.…”

“…Interaction of an ultrafast and high-power pulsed laser with a material surface has become a hot topic of research in recent years and is already being used in many industrial technologies, for instance microfluidic, photonic and biomedical devices [1,2]. Any substance under such laser irradiation experiences phase transitions into all states, including plasma which in turn may change chemical composition due to nuclear reaction [3,4].…”
