Photocatalytic MoS2 with visible light response is considered as a promising bactericidal material owing to its non–toxicity and high antibacterial efficiency. However, photocatalysts always exist powder, so it difficult settle on the metal surface, which limits their application in aqueous environments. To solve this problem, ultrasound sodium dodecyl sulfate (SDS) were introduced into co-deposition process of zinc matrix, that novel MoS2–Zn coatings obtained. In process, SDS strongly...

The Mg-6%Al-3%Zn and Mg-6%Al-3%Zn-(1%, 1.5%, 2%)In alloys were prepared by melting casting. Their microstructures investigated via metallographic energy-dispersive X-ray spectroscopy (EDS) analysis. Moreover, hydrogen evolution electrochemical tests carried out in 3.5 wt% NaCl solution aiming at identifying their corrosion mechanisms discharge behaviors. results suggested that indium exerts an improvement on both the rate activity of Mg-Al-Zn alloy effects grain refining, β-Mg17Al12...
The corrosion behavior and mechanical property of Mg–7Y–xNd (x = 0.5, 1.0, 1.5 wt%) alloys were investigated. microstructure precipitations studied by scanning electron microscopy, energy-dispersive spectrometry X-ray Diffraction. quantities the Mg12(Y,Nd) phase increased, whereas that Mg24(Y,Nd)5 decreased with increasing Nd-content. weight loss rate from 17.5020 mg cm−2 d−1 (36.7542 mm y−1) to 9.3744 (19.6862 y−1). electrochemical measurement also demonstrated similar tendency. in...
The corrosion behavior of Mg-Nd binary alloys in the harsh South China Sea environment was researched by scanning electron microscopy, energy-dispersive spectrometry and X-ray diffraction analysis. In order to explain mechanism, resistance analyzed weight loss rate electrochemical measurement laboratory. With a continuous enlargement Nd-content, Mg12Nd phases increased multiplied. Mg-0.5Nd alloy 0.0436 mg•cm−2•y−1 (0.0837 mm•y−1), whereas that Mg-1.5Nd 0.0294 (0.0517 mm•y−1) during exposure...
Abstract Rapid development of railway industry makes safety increasingly important. Wear, contact-impact, fatigue and corrosion are important factors initiating rail track degradation from the beginning, while attracts far less attention than other issues. Direct cost due to in China was 18.88 billion RMB, so definitely deserves more attention. This work has reviewed studies focussing exclusively on corrosion, including forms, protection detection technologies. General large surface is not...
The Pilling-Bedworth ratio of oxides preferentially formed from the precipitated phases in magnesium alloys were calculated. results showed that PBR value Nd 2 O 3 Mg 12 was 1.0584, and Y 24 5 1.1923.
