Abstract The objective of this research is to study the influence of deposition parameters such as gases mixing ratio O2/Ar on the structural and optical properties of the TiO2/SiO2 nanocomposite films synthesized using closed field unbalanced dc magnetron co-sputtering technique. The nanocomposite thin films were characterized using x-ray diffraction (XRD) to determine the phase structure, and Fourier transform infrared (FTIR) spectroscopy to investigate Si-O-Si, Ti-O and Si–O–Ti. functional groups. The UV-VIS. absorption spectra of the synthesized films reveal that the indirect energy band gap was found to be 2.75 eV. The mixing ratio of Oxygen and Argon (O2/Ar) gases has a pronounced controlling effect on the structural and optical properties of such nanocomposite.

Electrodeposition of only molybdenum onto substrates is difficult, therefore molybdenum is typically deposited with iron-based alloys such as nickel. The deposition of such alloys is known as an induced codeposition mechanism. The electrodeposition of nickel-molybdenum alloys using alkaline plating solutions is covered in this chapter. The mechanism for deposition of nickel-molybdenum is reviewed, as well as the influence of the plating parameters on the coatings. Characterization of the coatings by scanning electron microscopy and x-ray diffraction is discussed and how deposition parameters affect morphology, composition, and crystallite size. Nickel-molybdenum alloys offer enhanced corrosion protection and mechanical properties as coatings onto various substrates. A survey of the resulting hardness and Young's modulus is presented for several research studies. Corrosion parameters for several studies are also compared and show the percentage of molybdenum in the coatings affects these values.
