TL;DR: In this article, the chemical, morphological characterization and identification of the phases on the spangles were examined by scanning electron microscopy, backscattered electron imaging (BSE), atomic force microscopy (AFM), energy dispersive spectroscopy (EDS) and X-ray diffraction analysis (XRD).

TL;DR: In this paper, the morphology and growth behavior of intermetallic compound layers at the interface between solid nickel and liquid zinc were observed and analyzed by SEM and EDS, and it was found that the kinetics of the intermetall compounds growth follows a parabolic law of time, as controlled by the diffusion mechanism.

TL;DR: In this article, a comprehensive plating promoter treatment process and apparatus for hot galvanizing production line is described, which includes continuously pumping the solution from the plating promoting tank into the treating pot, pumping the solutions from the dezincing tank and the smoke dust pot with a metering pump, adding ammonia water under the control of a pH metering and controlling system, blasting air to oxidize the bivalent iron in the solution into trivalent iron with the oxygen in the air to form ferric hydroxide precipitate, separating in the sloping plate precip

TL;DR: In this paper, an electroless nickel pre-plating and hot post-galvanizing method for controlling the coating thickness of the silicon-containing reactive steel, which means first performing electroless Nickel plating and then hot dip galvanizing on a silicon-component reactive steel part, is presented.

TL;DR: In this article, the change in the microstructure of the galvanized coating on the steel and the change of α-Fe/Γ interface were studied and it was shown that excessive silicon accumulates on the surface of the steel substrate due to the low solubility of silicon in the Γ layer after the Fe layer is depleted by the increasing growth of the compound layers.
