[ 1 ] - Dip coating of silica layer on melt-spun Finemet ribbons: surface morphology and electrical resistivity changes
In this study, melt-spun Finemet ribbons were coated by a thin layer of SiO2 using dip coating method. Amorphous ribbon prepared by melt spinning method and dip coating were done by using a solution of tetraethylen orthosilicate as a SiO2 precursor, ethanol as solvent and distilled water for hydrolysis. Different thicknesses of SiO2 layer, namely 304, 349, 451, 526 and 970 nm were obtained prop...
[ 2 ] - Magnetic and Electrical Properties of Nanocrystalline Fe85Si10Ni5/Phenolic Resin Soft Magnetic Composites
In this work, nanocrystalline Fe85Si10Ni5 soft magnetic powders were prepared by mechanical alloying and subsequent annealing to reduce the internal stresses and lattice strains. The powders were mixed with phenolic resin and warm pressed to produce nanostructured soft magnetic composites. The effect of annealing time and temperature on the crystalline structure, microstructure and magnetic pro...
