The effects of process atmosphere oxygen partial pressure (pO2) on the preimmersion surface structures, interfacial reactive wetting products, and mechanisms two prototype (0.15–0.20)C–(5.6–5.9)Mn–(0.4–1.9)Al–(1.1–1.5)Si–(0–0.6)Cr (wt%) third-generation advanced high-strength steels during continuous hot-dip galvanizing are determined. In this study, two-stage thermal processing routes employed...

In hot dip galvanizing, several parameters such as chemical composition of coating bath, immersion time and surface roughness of specimens could affect microstructure and properties of coating. In this article, the effect of aluminum content, immersion time and surface roughness on structure and properties of alloy layers have been investigated. Specimens of low carbon silicon-free steel with d...

This scientific paper aims to determine the optimal economic roughness of galvanized surfaces by studying influence turning surface on quality galvanizing. The thickness zinc layer, its corrosion resistance, and precision parts were also examined. S235J0 steel samples processed using a operation obtain different values. Three galvanizing technologies, galvanic galvanizing, hot dip with centrifu...

The paper considers the technological features of thermodiffusion galvanizing fasteners in a powder mixture containing main waste hot it is gartzink. advantages preliminary fluxing over thermal diffusion zinc plating are noted. microstructure obtained layers on steel 40Х was studied, saturation kinetics and quality resulting were

When hot-dip galvanizing a square hollow section column, it is necessary to provide holes in the diaphragms. These affect local rigidity and strength of beam column connections. It requires evaluation formulae properly design hole diameter plate thickness In this paper, behavior connections failure mode examined by loading tests. The shortage test parameters supplemented performing finite eleme...
