In this study, MAO process, which is one of the surface coating methods, was applied to 7075-T6 Al alloy in a thin thickness and relationship between its mechanical properties compared uncoated state investigated. Surface microstructure images prepared samples, from cross section eds analysis were measured by scanning electron microscope (SEM). With XRD analysis, peaks material on made determin...

Thermal spray coatings are widely used in many applications, and the adhesion effect at coating/substrate interface plays an important role during service life. The thermal spraying coating substrate is primarily combined by a mechanical seizure effect. In this work, strategy to generate interfacial metallurgical bonding proposed. Plasma with wire feeding was adopted increase size of sprayed pa...

The surface finish was extensively studied in usual machining processes (turning, milling, and drilling). For these processes, the surface finish is strongly influenced by the cutting feed and the tool nose radius. However, a basic understanding of tool/surface finish interaction and residual stress generation has been lacking. This paper aims to investigate the surface finish and residual stre...

In this work, effects and mechanism analysis of samarium acetate ytterbium on enhancing the electrochemical corrosion performance aluminum-based anode for aluminum-air batteries in 3.5 wt.% NaCl are studied by methods such as weight loss tests, measurements, galvanostatic discharge tests microscopic morphology analysis. The results show that ideal electrolyte additives, exhibit obvious inhibito...

in this study, the effect of temperature on the diffusion welding of az31 magnesium alloy and 7075 aluminum was discussed. diffusion welding temperature was the most important parameter since all mechanisms are sensitive to temperature in diffusion welding method. intrusive contacts between the two alloys at temperatures of 430, and 440 °c 450 and took 60 min. in all tests constant pressure and...

The deformation of aeronautical monolithic components due to CNC machining is a bottle-neck issue in the aviation industry. The residual stress releases and redistributes in the process of material removal, and the distortion of the monolithic component is generated. The traditional one-side machining method will produce oversize deformation. Based on the three-stage CNC machining method, the q...

In this study, the effects of two geometrical parameters re-entrant auxetic cells, namely, internal cell angle (θ) and H/L ratio in which H is height, L length, have been studied on variations Poisson’s fatigue life Aluminum 7075-T6 structures. Five different values both θ were selected. Numerical simulations predictions conducted through use ABAQUS (version 2022) MSC Fatigue 11.0) software. Re...
