In the present study, physical characteristics of some dry bean cultivars (Sarikiz, Basara and Horoz) a local population grown in Konya province Turkey were determined an experimental test set up was used to investigate flow rates on different surfaces (galvanized sheet, plain sheet painted iron) conveyor channel angles (24 0 , 28 32 36 ). Sarikiz, Horoz respectively at 10.85, 9.63 9.12% moistu...
background: galvanization is the process of coating steel or cast iron pieces with a thin layer of zinc allowing protection against corrosion. one of the important hazards in this industry is exposure to zinc compounds specially zinc oxide fumes and dusts. in this study we evaluated chronic effects of zinc oxide on the respiratory tract of galvanizers. method : 188 workers were selected from a ...
In this paper, bare spot defects in hot-dip galvanized sheets were studied in terms of the microstructure and their influence on the corrosion and mechanical properties. Surface characteristics and microstructural features were examined by scanning electron microscopy equipped with energy dispersive spectroscopy microanalysis system. The results showed that the major cause of the bare spots was...
We studied atmospheric corrosion on Rapa Nui Island, using galvanized and non-galvanized SAE 1020 steel samples exposed racks. also added Charpy of both materials to directly determine the effect rate these materials' impact toughness. The results indicated a correlation between toughness loss in materials. In study, we could demonstrate from increased insular population growth contaminants whi...
In the study, effects of welding parameters on microstructure and mechanical properties electrical resistance spot welded TBF/DP600 steel sheets 1.2 mm thickness were investigated. TBF used in study was both with without electro-galvanized. Microhardness measurements tensile shear tests taken as basis determining properties, while optical microscope for microstructural characterization. The nug...
In the paper the methodology and test results of field and laboratory corrosion tests of steel earthing rods with zinc galvanized coatings and copperbonded coatings are described. The corrosion rate and level of corrosion damage of earthing rods with two different protective coatings have been compared as well some conclusions related to reliability and assessment of technical life time of st...
