The Zn-Ni-TiO2 composite coatings were developed on mild steel by electrodeposition method. The bath constituents (ZnSO4.6H2O, NiSO4.6H2O, TiO2, thiamine hydrochloride) and operating conditions (temperature and pH) were optimized by Hull cell method, for peak performance of the coating against corrosion. The coatings were prepare...

Zn4Sb3 is shown to be entropically stabilized versus decomposition to Zn and ZnSb through the effects of configurational disorder and phonon free energy. Single-phase stability is predicted for a range of compositions and temperatures. Retrograde solubility of Zn is predicted on the two-phase boundary region between Zn4Sb3 and Zn. The complex temperature-dependent solubility can be used to expl...

The outermost nanometres of a poly(vinylidene difluoride) (PVdF) based coil coating have been investigated using X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS). A reference PVdF based coating formulation and three variations of this formulation were characterised by XPS. The addition of flow agent and/or acrylic co-polymers induced significa...

Heavily In-doped CdTe and ZnTe crystals are investigated using perturbed γγ-angular correlation experiments. By means of characteristic electric field gradients, it is shown that in the Cd (Zn) poor regime, the compensation is governed by A-center formation. After annealing in Cd (Zn) rich atmosphere, the formation of DX-centers is observed and identified as the prevailing compensation mechanis...

Tightly bonding of bioactive coating is the first crucial need for orthopaedic implants. This study describes a novel and convenient technique to prepare bioactive coating with high adhesion on orthopaedic substitutes made of polymeric matrix. Here, a chemical corrosion method has been adopted to fabricate a coating on the surface of injection-moulded polyamide66 (PA66) substrates by corrosive ...

At present, the common protection technology of power-transmission and transformation equipment is mainly coating hot-dip zinc protection. However, due to low adhesion epoxy zinc-rich coating, poor compatibility with top paint, environmental pollution, complex processing, high energy consumption other defects process, its development limited. In view above deficiencies, new anti-corrosion mater...

Taknar Polymetal (Cu-Zn-Au-Ag-Pb) Deposit: A New Type Magnetite-Rich VMS Deposit, Northeast of Iran

The study on the surface morphology and crystal orientation of Zn-0.5Sn coating could offer some guidance to improve performance hot-dip galvanizing coating. In this paper, a scanning electron microscope (SEM) an energy dispersive spectrometer (EDS) were used analyze typical element distribution spangles. texture was analyzed by X-ray diffraction (XRD). Electron backscatter (EBSD) results show ...
