“…However, a good adhesion of the coating to the substrate is essential for a successful application [1]. Hard coatings fabricated by habitual physical vapor deposition have a poor film quality due to porous microstructure and weak adhesion [2]. Also, adhesion problems related to the different thermal expansion coefficients of the coating and substrate material were also observed [3].…”

AbstractZirconium thin films were grown on high carbon steel substrates EN C100 (1 %wt. of carbon) by RF magnetron sputtering. In order to study the reactivity of the film/substrate system as a function of the temperature, one hour vacuum annealing was carried out for different temperatures between 600°C and 1100°C. The films were then analyzed by X-ray diffraction, scanning electron microscopy, glow discharge optical emission spectroscopy (GDOES) and nanoindentation.The obtained results showed a progressive transformation of zirconium film to zirconium carbide.Carbon atoms diffusion from substrate toward the film induced this transformation. The sample annealed at 900°C exhibited the best mechanicals properties (H =17 GPa and E = 220 GPa).Samples treated at higher temperature were affected by oxidation and high microporosity. Even if the conversion is uncomplete, annealing significantly promotes adhesion of the film on the substrate.

“…The TiN layers grow in a Ðne-grained polycrystalline columnar structure with a 15È20 nm column width that was determined by crosssection transmission electron microscopy (TEM). 23 The reason why the samples were prepared in this way instead of depositing the TiN coatings on massive iron is that the possible Fe bulk contribution to the ICEM spectra in the corroded samples is minimized, thus enhancing the contribution of the species formed at the TiN/Fe interface.…”

“…Reference coatings show columnar growth with increasing grain size toward the film surface. The average column width varies between 15 nm for NbN and 150 nm for CrN, 56 as summarized in Table I. Both CrN and TiN have columns extending through the entire film thickness, but TiN shows highangle boundaries whereas CrN has low-angle boundaries columns.…”

In situ scanning electron microscopy indentation studies on multilayer nitride films: Methodology and deformation mechanisms

Systematic studies of the deformation mechanisms of multilayer transition metal nitride coatings TiN/CrN, TiN/NbN, and NbN/CrN, and corresponding reference coatings of TiN, NbN, and CrN deposited by a direct current (dc) magnetron sputtering process onto silicon h100i have been performed. Mechanical characterization was conducted using a combination of microindentation and nanoindentation in the load range 30 to 150 mN and 0.5 to 3.5 mN, respectively. For both load ranges, scanning electron microscopy (SEM) in situ indentation was used to observe the indentation process including any pileup, sink-in, and fracture mechanisms specific to each coating. The coatings' microstructure, both before and after indentation, was analyzed using transmission electron microscopy (TEM). It was possible to both correlate the indentation load-displacement response to surface roughness effects and fracture modes (substrate and film cracking) and observe deformation mechanisms within the coatings.
