The effect of Al on the corrosion resistance behaviour of Pb-free Sn–1.0Ag–0.5Cu–xAl solder (x 1⁄4 0.2 wt%, 0.5 wt% and 1.0 wt%) in 5% NaCl solution was investigated by using potentiodynamic polarization and salt spray exposure. Passivation behaviour was evident in all the solder formulations containing Al, compared to the base SAC solder. FESEM and XRD results revealed that more dense passive ...

In this study, we aim to investigate the effect of galvanic corrosion on mechanical properties aluminum-CFRP adhesive joints. Aluminum-CFRP, aluminum-aluminum, and CFRP-CFRP joint specimens were prepared. Subsequently, subjected accelerated aging treatment in a salt spray environment, tensile shear strength, transition failure surface deposition state components products with time quantitativel...

Different amounts of nanoclay were incorporated into the acrylic resin matrix at 0, 1, 3, and 5 wt.% loadings. The coatings were applied on low carbon steel plates. Optical microscopy, sedimentation test, transmission electron microscopy, and X-ray diffraction were employed to investigate the dispersion of nanoclay in matrix. The corrosion resistance of coatings was evaluated by electrochemical...

The influence of additives inducing viscoelasticity in diesel fuel, on the in-nozzle cavitation evolution and expelled spray morphology has been quantified by high-speed, diffused back-light schlieren imaging applied to two single-hole true-scale transparent injectors straight tapered orifice layouts (so-called Spray C D engine Combustion Network), as well a five-hole configuration (Spray M). M...

Abstract In the production of fermented cabbage, cell juice cabbage is released, which highly saturated in biologically active compounds, but considered as a by-product. The aim this study was to evaluate quality parameters dehydrated using maltodextrin coating agent at various concentrations. experiment, used — spray dried on horizontal spray-dryer and maltodextrin, different concentrations (0...

garden asparagus is thought originally to be native in eastern Europe or western Asia, perhaps in or near the Caucasus, although it is widely naturalised inland and on the coast.” But wild asparagus is becoming increasingly rare. It is found only on the coasts of northern Spain, northwestern France, Belgium, the Netherlands, the UK and Ireland. And some of the known populations comprise as few ...
