Aluminum alloys such as Al 5083 have primary potential for lightweight structural application in automotive and aerospace industries. This paper addresses the mechanical and tribological properties and corrosion resistance of chromium nitride coatings deposited on Al 5083 that can be used for development of applications of aluminum 5083 alloy. The CrN coatings of 1 μm thickness were deposited b...

Deposition of coatings of aluminum, aluminum nitride and aluminum carbide on particulate carbon materials by means of an atmospheric pressure microwave plasma fluidized bed process is reported. Two types of short carbon fibers and a monocrystalline diamond powder were used as substrate. As source of aluminum trimethylaluminum was utilized with nitrogen and argon/hydrogen (5 vol% H2) serving as ...

Ž . Ž . The growth of cubic aluminum nitride AlN and cubic gallium nitride GaN is studied. The effects of ambient pressure and substrate temperature on the structure of the AlN and GaN films are systematically investigated. It is shown that the films are amorphous when the temperature and the pressure are too low. Cubic AlN is obtained at a temperature of 8008C and a pressure of 0.2 Torr. Cubic...

Piezoelectric aluminum nitride thin films were deposited on aluminum-molybdenum (AlMo) metallic nanocomposites using reactive DC sputtering at room temperature. The effect of sputtering parameters on film properties was assessed. A comparative study between AlN grown on AlMo and pure aluminum showed an equivalent (002) crystallographic texture. The piezoelectric coefficients were measured to be...

An Aluminum Nitride (AlN) MEMS resonator technology has been developed, enabling massively parallel filter and oscillator arrays on a single chip. Low loss filter banks and resonator arrays covering the 10MHz10GHz frequency range have been demonstrated, as has monolithic integration with inductors and CMOS circuitry. The high level of integration enables miniature multi-band, spectrally-aware a...
