cover - provide with a covering or cause to be covered; "cover her face with a handkerchief"; "cover the child with a blanket"; "cover the grave with flowers"
They examine such topics as experimental research on mineral processing on a certain lead-zinc ore, the interface constraint effect and stress relaxation in nano-sandwiched thin film, preparation and properties of conductive epoxy resincomposites, the two-photon selective reflection spectroscopy of confined atomic vapor at the interface with a ferroelectric layer, the mechanism of aluminizing aided by mechanical energy, detecting ascorbic acid with microchip electrophoresis, and foaming polystyrene with supercritical carbon dioxide.
Lower temperature aluminizing treatments of the SMAT samples were investigated by scanning electron microscope and X-ray energy dispersive spectroscope.
The corrosion and oxidation usually occurs in the operation of parts like gas turbine vanes."According to the previous studies, formation of nickel nanostructure for aluminizing process, an industrial process for production of coatings resistant to high temperature oxidations, makes the formation of coatings at considerably lower temperatures possible compared to the current methods and shortens the formation time of aluminide coatings," Ali Mohammad Rashidi, professor at Razi University, told INIC.Samples of nanostructured and microstructured nickel and nickel-tungsten alloy were supplied and underwent low temperature-high activity aluminizing treatment.
A unit was put into operation in 1972 in Middle-town, which was designed for aluminizing strip of 0.4-2.5 mm thickness and up to 1525 mm width with two changeable baths for production of hot-aluminized steel of type I (AlSi) and type II (Al) [10].
A new unit for hot galvanization (aluminizing) of 270 thou t/year productivity was installed in Fol-lansbee by joint American-Japanese company <<Willing-Nisshin>>.
He starts with a 16-inch piece of porthole glass and a subdiameter tool, and demonstrates the rough grinding, fine grinding, polishing, figuring, and aluminizing of the mirror.
