Nanocomposite thin films composed of a TiO2 matrix doped with noble metals nanoparticles (MNPS), Au and Ag, were deposited on Si (100) and glass substrates by dc magnetron sputtering. The samples were annealed in a protective atmosphere at temperatur

A new category of hard nanocomposite coatings with adjustable improved hardness or enhanced toughness consisting of nanocrystalline (nc-) titanium nitride grains embedded in an amorphous (a-) metallic intergranular nickel phase i.e. nc - TiN / a - Ni

TiN–Ni films (∼ 0.5 μm thick) were deposited on (100) Si wafer and 304L stainless steel, using an ultrahigh vacuum dual ion beam sputtering technique, in order to obtain nanocomposite films with nanograins of TiN surrounded by an intergranular N
