“…[ 95,155–157 ] At the University of Cincinnati, Vasudevan and co‐workers performed LSPwC on AISI 304 austenitic stainless steel, Inconel 718, and AA5083 aluminum alloy. [ 158–160 ] The results showed that LSPwC significantly improved the pitting resistance of the specimens and contributed to the extended fatigue life. Note that although LSPwC increases the surface roughness of the specimen, the surface roughening is controlled, so the increase within a certain range does not affect the corrosion resistance of the specimens.…”

“…In addition, according to a recent study by Kaufman and Vasudevan, LSPwC significantly reduced the intergranular corrosion rate compared with LSP. [ 159 ] Wang et al [ 155 ] also found that although LSPwC improved the surface roughness of NiTi alloy, its wear resistance was also imoroved. LSPwC is appealing for industrial applications because it can significantly increase process efficiency.…”

Many aviation accidents are caused by the failure of aircraft engine components, and engine blades are especially vulnerable to high‐cycle fatigue fracture in severe working environments as well as to impact damage caused by foreign objects. To address this problem, the United States took the lead and has been successful in implementing laser shock peening (LSP) as a surface treatment for aircraft engine components to enhance their fatigue performance. This review provides an overview of the development of LSP for use in treating aircraft engine components over the past three decades, with a brief introduction to the development of high‐energy pulsed lasers for LSP. A particular focus of this review is on the limitations and challenges associated with the application of LSP for treating critical aircraft engine components. It is hoped that this review serves as a reference for future research and development that can lead to better performance of these components.

Effects of Laser Shock Peening on Corrosion Resistance of Additive Manufactured AlSi10Mg

Mechanical properties of Al alloys make them an ideal candidate for different sections of marine, aerospace, automotive, etc. industries. Recently taking the advantages of additive manufacturing (AM), many complex infrastructures/components can be fabricated with very high design freedom via Al alloys. Although Al alloys have good natural corrosion resistance, however improving this property attracts lots of attention in the past few years. Post-processing methods can play a key role for addressing the issues related to internal and surface anomalies associated with as-built AM parts. Generally, these anomalies have detrimental effects on mechanical properties. In the present study, the effect of laser shock peening (LSP) treatment with different laser pulse overlaps and energies was investigated comprehensively on microstructure, surface texture, porosity, hardness, residual stresses as well as corrosion resistance of laser powder bed fused (L-PBF) AlSi10Mg samples. LSP provides strain deformation on the surface, and the deformation enhances by laser beam energy. LSP1 (laser energy of 1.5 J and 50% overlap) and LSP3 (laser energy of 4.5 J and 50% overlap) introduce maximum local strain of 7.5 and 10.7, respectively. The surface roughness of as-built state µm in terms of Rv was effectively diminished to 16.33 after LSP6 (laser energy of 4.5 J and 75% overlap). The results indicated that due to the modified surface texture, improved hardness and induced high compressive residual stresses in the surface layer. (surface hardness improvement and inducing high surface compressive residual stresses were obtained after LSP6 up to 26% and −289 MPa, respectively); the LSP treated samples exhibited higher corrosion resistance with the corrosion rate decreasing down to 50% as compared to the as-built state.

“…The 5XXX series aluminum alloys (Al-Mg) are often employed in ship construction thanks to their high corrosion resistance, good weldability, and good strength. In particular, aluminum alloys lower than about 3% Mg (i.e., 5052) are not sensitized and susceptible to intergranular corrosion at elevated temperature [1,2]. Despite their extensive use in various industries, their applications are limited in parts to vigor frictions, mechanical loading, and thermal loading due to poor wear properties [3,4], mainly related to surface properties.…”

In this work, Al 2 O 3 , SiC, and TiB 2 ceramic coatings with different formulations were produced on the surface of AA5052 matrix by gas tungsten arc welding (GTAW). The corrosion behavior of the composites and the base metal (BM) was evaluated in a solution of 0.5 M H 2 SO 4 with electrochemical techniques such as open circuit potential (OCP) monitoring, potentiodynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS). The morphology of the cladded surfaces was monitored by scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS). Based on the PDP and EIS results, BM had the lowest corrosion rate in the 0.5 M H 2 SO 4 solution. All composite coatings shifted to higher corrosion rate values than that of BM, indicating that AA5052 composites had lower corrosion resistance compared to the BM. SEM images of the corroded surface of BM exhibit minimum pitting corrosion in sulfuric acid media. According to electrochemical studies, AA5052/Al 2 O 3 + SiC + TiB 2 composite had the lowest corrosion resistance due to the formation of micro-galvanic sites on the aluminum matrix surface. However, the AA5052/Al 2 O 3 + TiB 2 composite showed the best corrosion performance compared to other composites. In general, by adding SiC and TiB 2 ceramics to Al 2 O 3 and fabricating binary composites, the corrosion resistance of AA5052/Al 2 O 3 composite is improved. Although the corrosion resistance of AA5052 composites is lower than the BM, their higher surface hardness makes their use justified in applications where high mechanical properties are required if the environment is not too aggressive.
