Ni-W-P ternary coating was successfully deposited on AZ91D magnesium alloy by electroless plating with low energy consumption. The effect of Na2WO4 concentration the microstructure, deposition rate, corrosion behavior, adhesion force, porosity test and micro-hardness coatings were evaluated. Results reveal that when is 15 g/L in solution, average thickness 17 μm uniform dense, content phosphoru...

In this work, Ni-W/diamond composite alloy coatings were successfully fabricated on low carbon steel by using direct current (DC) electrodeposition. The Ni-W molar ratio was varied in the range of 0.22–2 plating bath. effect variation microstructure, mechanical properties and tribology analyzed. obtained results show that W content deposition rate tends to decrease from 19.02 at. % 2.1 34.86 µm...

In the marine environments, NiCrAlY coatings with high content of Cr would suffer much severer corrosion due to effect NaCl. Thus, NiSiAlY different Si were proposed and deposited on Ni-based superalloys by multi-arc ion plating. The as-deposited coating was mainly composed γ’-Ni 3 Al phase a small amount β-NiAl phase. NaCl-induced hot tests performed at 500°C, 600°C, 700°C, respectively. Compa...

The severe lithium (Li) dendrite growth leads to poor cycling stability and serious safety hazards of Li metal batteries, which completely impedes their practical applications. Herein, a novel nucleation-diffusion-growth mechanism based on Li-Sn alloy/Li3N electrolyte (LS/LN) composite interface layer is proposed, synergistically guides the horizontal deposition suppress vertical side reactions...

background: the entrance of toxic compounds into wastewater treatment plants (wwtps) can induce disorder in their biological units. therefore, it is necessary to determine the sources of toxic wastewaters. in this study, the toxicity of the wastewater of 3 metal plating industries was assessed using sequencing batch reactor (sbr) bacteria. methods: to obtain the 1-1000 ml/l concentrations, the ...

Electroless nickel plating is a widely used plating method in many industries. The usability of the coating is, however, restricted by the control problems related to the electroless nickel plating process. To ensure deposit quality, the transcendent properties of electroless nickel deposit should be accurately controlled during plating, which is challenging because of the spontaneous, unstable...
