An AlCrFeNiCuCo high-entropy alloy (HEA) coating was synthesised on an aluminium substrate by laser cladding. Samples were characterised using optical microscope, X-ray diffraction, scanning electron microscopy with energy-dispersive spectroscopy, a microhardness tester, and electrochemical workstation. The results showed that the interface between cladding layer matrix sound, while HEA consisted of BCC FCC solid solutions Al-rich phase resulting from dilution. microstructure clad comprised...
Balling effect is an inevitable defect during Selective laser melting (SLM) process, and it deteriorates the mechanical corrosion properties of resulting parts. In this work, SLM process used with various inclination angles to fabricate samples. The deep relationship between selective as-SLM fabricated parts established understand angle on surface roughness, microstructure evolution, 316L stainless steel components. Results show that Ra value increased increasing angles. Inclination play...
Abrasive flow machining (AFM) process and ultrasonically assisted AFM technique (UAAFM) were carried out to polish micro-channel internal faces produced by selective laser melting (SLM). Both numerical simulation experimental studies investigated. Simulation results confirmed that the distribution of velocity, absolute pressure, turbulence intensity inside S-shaped exhibit significantly different. After loading ultrasonic-vibration, cavitation can indeed enhance intensity. As ultrasonic...
In order to investigate the influence of tilt angles on residual stress, densification behavior, microstructure and mechanical properties during selective laser melting (SLM), samples are fabricated with five (0, 30, 45, 60 90 degrees) in this work. Results show that average stress 0 degree arrive 400 MPa which is almost 2 times higher than inclination specimen. Two mechanisms used explain formation namely temperature gradient mechanism (TGM) cool-down phase. With increment angles, layer...
This study aimed to investigate the effects of laying angles (0°, 15°, 30°, 45°, 60°, 75° and 90°) on surface roughness, density behaviour, residual stress, mechanical properties 316L stainless steel components fabricated by selective laser melting. The findings revealed that 15° samples exhibited best quality, while 90° had a roughness up 18μm due staircase effect balling behaviour. stress decreased gradually as angle increased. 0° reached 99.92%, whereas were only 99.62%. good tensile...
To commercialize the rechargeable zinc-air (Zn-air) battery, it is desirable but challenging to design highly active, low-cost, stable, and earth-rich bifunctional electrocatalysts for oxygen reduction reaction (ORR) evolution (OER) replace rare, expensive, unstable noble-metal electrocatalysts. Herein, two MOFs are combined under electrostatic interaction pressure by way of Ball milling. Then, after post-processing including calcination, acid pickling, N doping, bimetal (Fe Co) triple-doped...
