“…Osteosynthesis plates also suffer from failure, caused by fatigue fractures, usually initiated at the surface. Fatigue strength and bending strength of materials can be enhanced after shot-peening and SMAT treatment as confirmed by previous publications Starker et al, 1991, Bauer M et al, 2013, Huang and Han, 2013Torres and Voorwald, 2002). Our data showed a significant mechanical strength improvement of Indonesian-made osteosynthesis plates upon surface modifications.…”

“…Cyclically stressed substrates requiring TS coatings are often shot peened prior to coating application to store compressive residual stress at the substrate material surface, which is the most likely place for fatigue cracks to initiate and propagate. 29 Surface roughening through grit blasting, which is the a standard surface preparation for enhancing TS coating adhesion, induces compressive residual stresses at the substrate surface, although it is not the primary goal. Initial deposition of high kinetic energy particles will continue to peen the substrate surface, although local heating and possible stress relief of these previous steps may take place.…”

Thermal spray coatings are used extensively for the protection and life extension of engineering components exposed to harsh wear and/or corrosion during service in aerospace, energy, and heavy machinery sectors. Cermet coatings applied via high-velocity thermal spray are used in aggressive wear situations almost always coupled with corrosive environments. In several instances (e.g., landing gear), coatings are considered as part of the structure requiring system-level considerations. Despite their widespread use, the technology has lacked generalized scientific principles for robust coating design, manufacturing, and performance analysis. Advances in process and in situ diagnostics have provided significant insights into the process-structure-property-performance correlations providing a framework-enhanced design. In this overview, critical aspects of materials, process, parametrics, and performance are discussed through exemplary studies on relevant compositions. The underlying connective theme is understanding and controlling residual stresses generation, which not only addresses process dynamics but also provides linkage for process-property relationship for both the system (e.g., fatigue) and the surface (wear and corrosion). The anisotropic microstructure also invokes the need for damage-tolerant material design to meet future goals.

Abstract-Shot peening is a process of cold working a part that increase its resistance to metal fatigue and some forms of stress corrosion. Shot peening causes plastic deformation in the surface of the peened part and leads some changes in mechanical and metallurgical properties of it. Artificial intelligence (AI) systems such as artificial neural networks (ANNs) have found many applications to predict and optimize the engineering problems in the last few years. In present study effects of SP on mechanical and metallurgical properties of 18CrNiMo7
