In this paper, the behavior of corrosion in phosphated galvanized steel without defect and with surface is evaluated electrolyte solutions sodium chloride at a concentration 3% sulfate 0.1 M objective simulating marine environment presence chlorides, sulfates for industrial environment. experimental methodology, samples are used, each were exposed sulfate. The was electrochemical techniques Lin...

Located in Guangxi Province, China, the Liuzhou Iron and Steel Company is one of China’s leading suppliers of plate steel to its shipbuilding industry. Also exporting to countries such as Japan, Germany, Singapore and Thailand, the company is now capable of producing one million tons of steel per year, owing to a series of recent technical innovation projects. Foremost among these is an ongoing...

In this research an experimental study has done for testing the thermal performance of selective surfaces used in solar collectors substrate iron, galvanized iron and aluminum which are commercially available. The coating process samples two ways, electroplating chemical spray pyrolysis. results test these comparing with a sample without paint other black shines For electroplated samples, diffe...

Mantle oxygen fugacity exerts a primary control on mass exchange between Earth's surface and interior at subduction zones, but the major factors controlling mantle oxygen fugacity (such as volatiles and phase assemblages) and how tectonic cycles drive its secular evolution are still debated. We present integrated measurements of redox-sensitive ratios of oxidized iron to total iron (Fe3+/SigmaF...

The metal fume fever (MFF) is an inhalation fever syndrome in welders of galvanized steel, who join and cut metal parts using flame or electric arc and other sources of heat. Inhalation of certain freshly formed metal oxides produced from welding process can cause MFF as an acute self-limiting flulike illness. The most common cause of MFF is the inhalation of zinc oxide (ZnO). The inhalation of...

A three-dimensional (3D) finite element (FE) model is applied to predict the temperature evolution in the laser welding of galvanized high-strength steels in a zero-gap lap joint configuration. A rotary Gaussian volumetric heat source model is introduced to simulate the laser energy input. The temperature data measured by thermocouples are used to verify the boundary conditions of the thermal m...

Biohydrometallurgy has been defined as a collection of techniques that involve the use microbial metabolisms, such bacterium Acidithiobacillus thiooxidans, for extraction metals. Therefore, in current study, we tested potential pure culture A. Thiooxidans removal zinc and iron from galvanized waste automotive industry. Starkey medium was employed added 0.5% w/v solid sample, incubation took pla...

This study is a detailed failure analysis of galvanized high carbon steel wires, which developed coating cracks during the torsion test performed as a quality control at the end of the manufacturing process. Careful visual inspections showed that the cracks are already present in the coating before the torsion test. In order to explain the origin of these cracks, systematic metallographic inves...
