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...

We explore the controllability of nonadiabatic alignment in dissipative media, and the information content of control experiments regarding the bath properties and the bath system interactions. Our approach is based on a solution of the quantum Liouville equation within the multilevel Bloch formalism, assuming Markovian dynamics. We find that the time and energy characteristics of the laser fie...

Corrosion tests of 316L and two intermetallic compounds Fe3AI and FeCrSi in industrial Galvanizing (Zn-0.18Al), GALFAN (Zn-5AI), GALVALUME (Zn-55AI), and Aluminizing (AI-8Si) baths and lab-scale static baths were conducted. In on-line tests in industrial hot-dip baths, 316L steel shows better corrosion resistance than Fe3AI in Galvanizing, GALFAN, and GALVALUME baths. The corrosion resistance o...

ni-p and ni layers multilayer coatings were applied to az31 magnesium alloy utilizing electroless and electrodeposition procedures. the aim of the project was to decrease cracks and increase corrosion resistance of the coatings. in order to compare the coatings, the effect of single layer electroless ni-p coatings with different thicknesses was also investigated. the microstructure and phase co...

Electrocrystallization of hydroxyapatite (HAp) on titanium was achieved by cathodic polarization in solution containing calcium nitrate and ammonium dihydrogen phosphate. The composition and pH of the bath were found to significantly affect the nature and surface morphology of the deposit. The effect of bath temperature was also studied. X-ray diffraction tests and microscopic inspections confi...

Nanowire is a cylindrical nano-structure with nanometer dimensions. In this research, the studied nanowire was made from the magnetic triple Ni-Fe-Co alloy.&#10 We utilized ordered porous anodic aluminum oxide as a template for the nanowire deposition. The nanowire arrays were electrodeposited in the cylindrical pores of the oxide layer by AC potential in a simple sulfate bath. Then the relatio...
