Nanostructured ZnO thin films were prepared by sol-gel dip coating technique. Zinc acetate and ammonium hydroxide were used as precursors and ethanol was as solvent. Ammonium hydroxide (NH4OH) solution was added drop-wise under vigorous stirring to obtain the sol-gel of different pH (varying from 6.9 to 7.2). ZnO thin films were obtained by dipping the glass substrates for few seconds and then ...

An X-ray diffraction technique was used to measure the residual stress in the surface of a specimen containing a coating of a NijAl intermetallic compound produced bythe SHS (Self-propagation High temperature Synthesis) method. The Ni3Al was using the coating material for spherical carbon cast iron substrate and austenite stainless steel substrate. Differences between the coefftcient of thermal...

Rutherford backscattering of energetic particles can be used to determine the thickness of a coating of a low-Z material over a heavier substrate. Simulations indicate that 5 MeV alpha particles from an (241)Am source can be used to measure the thickness of a Li coating on Mo tiles between 0.5 and 15 μm thick. Using a 0.1 mCi source, a thickness measurement can be accomplished in 2 h of countin...

Background: Diamond turning is widely used in machining metals and semiconductors but the turning marks are incurred on machined components due to the mechanics of the technology. The marks are generally harmful to the systems comprising of the machined components. Therefore, the capability of ion beam planarization (IBP) to reduce turning marks of diamond turned metal surfaces was investigated...

The sol-gel method provides a wide variety of applications in the medical field. One these is formation coatings on metal implants. containing specific additive can enhance or improve existing surface properties substrate. In this work, titania were doped with two forms silver (AgNO3, Ag3PO4) and synthetic hydroxyapatite applied titanium samples by dip-coating technique. After drying slow firin...
