“…Therefore, the L 25 (5 5 ) orthogonal array is selected for this experiment. Exhaustive literature review on erosion behavior of polymer composites reveals that the above control factors largely influence the erosion rate of polymer composites . Analysis of the impression of each erosion test parameter is performed by using MINITAB 14.…”

Linz‐Donawitz sludge (LDS) are the microsized solid particles that are recovered after wet cleaning of the gas emerging from basic oxygen furnace during steel making. This article reports on the development of a new class of thermoset polymer composites filled with this industrial waste called LDS. It includes processing, characterization and solid particle erosion wear of epoxy composites filled with different proportions (0, 5, 10, 15, and 20 wt%) of LDS by solution casting technique. The solid particle erosion wear tests are performed on the prepared epoxy‐LDS composite specimens as per ASTM G76 using Taguchi's Orthogonal Arrays followed by the parametric appraisal of the wear process by Response Surface Methodology (RSM). A theoretical model is developed to estimate the erosion rate of these composites under different test conditions. The results obtained from the proposed theoretical model are found to be in good agreement with the experimental values under similar test conditions. Both Taguchi's analysis and RSM suggest that the filler content and the impact velocity are the most significant factors affecting the erosion rate of the composite specimens. POLYM.

“…The mechanical characteristics of 6082-T6 and 7075-T6 aluminium alloys have been utilised for finite element method (FEM) modelling applications, particularly when dynamic experiments are performed, such as car crashes, explosions, or ballistic strikes [20]. The relationships between erosion and corrosion are complicated, where both processes can either increase material loss or reduce overall wear [21,22]. Even though aluminium has excellent corrosion resistance, the external medium or certain alkalis can dissolve the oxide coating on the metal surfaces, resulting in corrosive metal when this film is damaged.…”

In this investigation, aluminium Al-2.5% Mg cast alloy was modified by adding 0.5 Ti and 0.1 B wt % modifiers to investigate their impact on the dynamic behaviour, as well as the mechanical and microstructure properties. The dynamic properties were analysed experimentally using a free vibration impact test and predicted using finite element methods. This study used a high-resolution polarised optical microscope to analyse the microstructure of the studied alloys and X-ray Powder Diffraction (XRD) analysis to determine the developed phases. Microstructure and mechanical properties were mostly enhanced as a result of grain refining during solidification and through the metal segregation process. The microstructure analysis of the modified alloy showed a significant improvement in the grain refinement; hence, the grains were 10 times finer than the cast alloy. The modified Al-2.5% Mg/Ti-B alloy demonstrated reduced inter-granular corrosion (IGC) than the Al-2.5% Mg standard cast alloy. By incorporating Ti-B modifiers into the composition of the cast Al-Mg alloy, the ultimate tensile strength (UTS), strain (ε), and hardness values (HV) were increased by 30.5%, 100%, and 18.18%, respectively. The dynamic properties of the modified alloy showed an enhancement in the resonant (fn) and damping ratio (ζ) by 7% and 68%, respectively. The predicted resonance frequencies of the investigated alloys showed results close to the experimental dynamic tests.

“…The damage degree of slurry erosion is related to many factors, such as impact speed, impact angle, particle size, and particle concentration. 15,16 The factors affecting the damage degree of the cavitation erosion are the sizes and numbers of cavitation holes. 17 The micro-cutting material removal mechanism of erosion wear was dominant for acute impact angles that show shallow deep and long craters.…”

The surface material of marine ship hulls suffers degradation by slurry erosion because of the impact of sands or solid particles in seawater. When the ship's moving speed increases, pressure is changed suddenly and cavitation erosion will occur. Therefore, in the ocean, the corrosion of the surface material of the ship hulls is a combined damage in a slurry erosion and cavitation erosion states. An experimental device, for the combined wear, capable of simulating the above working conditions is designed and manufactured. A combined wear test of various materials (Q235, DH32, and NM360 steels) is conducted. The results show that cutting furrows of the slurry erosion, pinholes of the cavitation erosion, holes of electrochemical corrosion, and their combined effect increase the material wear rates and areas. Ductile materials of high strength have less slurry and cavitation damage, and more corrosion damage. For ductile materials of low strength, slurry and cavitation wear play an important role. When the slurry impact speed is increased, the wear degree of materials is also increased. This experimental setup for the combined wear provides a strong support for the development of wear-resistant materials for ship hulls and the structural optimization of ship hulls.
