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 ...

Air knives with very different nominal values are used for various purposes in the industry. The uses of air include painting and coating stages automobile semi-finished products, as well many related to food production. One important sectors among these is continuous hot-dip galvanizing process, which a technique steel In addition, chemical process on paper thin layer another research topic. m...

In the industry, corrosion is a problem caused by electrochemical reactions between metals and their environment. The metal most commonly used iron (Fe). One way to overcome using Hot Dip Galvanizing (HDG) method. Before HDG process carried out, it necessary pretreatment, one of which fluxing process. Fluxing pre-coating so that more durable against dipping in solution ZnCl2 NH4Cl. PT Bondi Sya...

Accurate and computationally accessible models of liquid film flows allow for optimizing coating processes, such as hot-dip galvanization vertical slot-die coating. This paper extends a classic three-dimensional integral boundary layer model falling films (FFs) to account moving substrate (MS). We analyze the stability on vertically substrates in linear nonlinear setting. In analysis, we derive...

This modeling and optimization study applies a non-linear back-propagation artificial neural network, commonly denoted as BPNN, to model the most important mechanical properties such yield strength (YS), ultimate tensile (UTS) elongation at fracture (EL) during experimental processing of hot-dip galvanized dual-phase (GDP) steels. Once BPNN is properly trained, variables continuous galvanizing ...

There are different zinc coating technologies for corrosion protection of metal surfaces. The most widespread methods are hot dip galvanizing (zincing by dipping items into melted zinc) and electrolytic method by zinc deposition from the electrolytic solution (electroplating). The process of thermo-diffusion of a zinc coating is a newer process that forms a zinc alloy with the substrate. The US...

Hot-dip galvanizing is an efficient technique to control the corrosion of substrates. Producing blemish-free coatings a challenging task. Continuous work done on technology achieve excellent surfaces; thus, flaws are encountered at intervals in all continuous and galvannealed process. Most each very small galvanized defect can appear like draff particle, trapped actually tiny lot blemishes foun...

Micromagnetic NDT techniques like the measurement of the magnetic Barkhausen noise, the incremental permeability and the harmonic analysis of the tangential magnetic field allow deriving inspection procedures to online monitoring and control machinery parts and components in production processes in order to characterize mechanical properties like hardness, hardening depth, yield and tensile str...
