In this paper, tin whisker behaviour of electroplating tin coating was studied in different environments. Different thickness of electroplating tin coating on copper substrate had been tested. Two different environmental conditions had been applied :one temperature tests (70 °C)and one external force tests(70 °C /17.5N). The growth of tin whisker was studied by using scanning electron microscopy (SEM)...

ZnO nanostructures with different morphologies were grown on poly(ethylene terephthalate) fibers by a hydrothermal process at a low temperature of 93 o C. Then the ZnO nanorod decorated fibers were layer-by-layer coated with silica forming ZnO/SiO 2 core/shell structures on the textiles, and hydrophobized with hexadecyltrimethoxysilane. Scanning electron microscopy showed that introduction...
This research was involved with comparison study of tribological properties of a-C/Cr(N) multilayered coatings in micro-and nano-scales. The a-C/Cr(N) coatings were deposited on Si wafers and M2 steel substrates by unbalanced magnetron sputtering of one Cr and two C targets. Cross-section TEM analysis was used to determine the layer periodicity of the coatings. Nanoindentation was used to measure...
