In situ optical studies of metal deposition
نویسنده
چکیده
The importance of microscopic morphological control to metal electroand electroless deposition in several emerging technologies is discussed. The use of in situ optical probes of the morphological development of deposits is described. A number of these are reviewed to describe both the potential of each method and the available literature on studies of electroand electroless deposition. Included are optical probes of the mass transfer boundary layer, X-ray diractive and spectroscopic methods, ellipsometry, surface-enhanced Raman spectroscopy, infrared absorption spectroscopy, second harmonic generation and electrore ̄ectance.

Ex-situ studies on calcinations of structural, optical and morphological properties of post-growth nanoparticles CeO2 by HRTEM and SAED
Nanocrystalline particles of Cerium Oxide (CeO2) have been prepared by the chemical precipitation method using Cerium nitrate and Urea with a molar ratio of 1:2. The results revealed that the formation of CeO2 fine particles is influenced by molar ratio of metal nitrates to fuel. Well faceted CeO2 nanoparticles, were synthesized by thermal-assisted dissociation ...

In this research, an in-situ hybrid composite reinforced by Al3Zr and Al3Ti aluminide particles was fabricated by friction stir processing (FSP). The base metal was in the form of a rolled Al 3003-H14 alloy sheet, and zirconium and titanium metal powders were used as the reinforcements. Six passes of FSP were applied. Tensile strength and hardness of the base metal, as well as FSPed samples bef...
