Abstract: The research work was based on the study of the corrosion behaviour of the welded and un-welded medium carbon steel in sodium chloride solutions. The Sodium chloride solutions used are 1ml, 2ml, 3ml and 4ml for both welded and un-welded medium carbon steel in NaCl. The experiments were conducted in two ways, the weight loss analyses of measurements and using the electrochemical analyzer workstation to determine the potential dynamic of the... More

Abstract: The electrons of metallic iron atoms all have wave-particle duality. The electrons of each iron atom are particles in the liquid state, the solid state is fluctuating. The wave-particle duality parameters of each iron atom electron are different, there is a small difference, the same is gathered into one, become a single grain.The parameters of wave-particle duality are different. The crystallization temperature of liquid state is different from... More

Abstract: Bulk raw materials handling plant and sintering plant preparatory plants are established to receive, blend, stockpile, prepare and supply specified grades of raw materials for smooth operations of iron making plant (Blast furnace), steel making plant (Basic oxygen converter) and lime Plant(calcinations plant). The study discusses bulk raw materials handling and some general problem of scientific analysis and documentation of basic equipment... More

Abstract: The results of the study of oscillograms of voltage, current, pulsed electric power and energy input into the plasma of an overstressed nanosecond discharge between aluminum electrodes in argon and mixtures of nitrogen with oxygen (100-1) at pressures in the range of 13.3-103.3 kPa are presented, the emission plasma spectra are studied. It is shown that in mixtures of nitrogen with oxygen at atmospheric pressure, nanoparticles of aluminum oxide... More

Abstract: Chloride ions interact with aluminium in marine atmosphere to form corrosion cell. Due to this corrosion reaction occurs on their surface, aluminium is oxidized into Al3+. The corrosion reaction accelerates deterioration in metal and it produces galvanic, pitting, stress, crevice, intergranular corrosion. Chloride ions decrease internal and external strength of aluminium metal. It is a very important metal so used in different appliances for... More
