In this paper, the corrosion performance of galvanized steel was investigated in a simulated marine environment, under UV irradiation coupling with an alternating wet and dry cycle NaCl solution. The surface morphology, composition, before after different were investigated. results show that current density gradually increases resistance decreases as function cycles. Meanwhile, accelerates incr...

Abstract The current study is performed on three coated steel sheets to evaluate their mechanical and tribological properties. optical micrograph reveals the dark pearlite structure in ferrite matrix, whereas grain size analysis 4.07 μ m mean of ferrite. scratch hardness test better scratch-resistant properties for all experimental samples. Nanoscratch a decrease friction with increasing load f...

In many applications, such as fuel storage tanks and lines, galvanized steel is used a construction material which comes into contact with biodiesel. Considering that biodiesel more corrosive than petroleum diesel, studies aim to increase the corrosion resistance of in this environment are required. The present work investigates how chemical conversion treatment oxalic acid solution affects soy...

in this study, the physical properties (size, mass, volume, density, geometric diameter, sphericity and friction coefficient on galvanized steel and wood surface) and some mechanical properties of flesh and skin tissue (modulus of elasticity, bioyield stress, yield strain and toughness) for small, medium and large melons of ghasri variety were determined. means comparison was done by duncan’s m...

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...
