Structure and properties of PVD TiAlN and TiAlN/CrAlN coated Ti(C, N)-based cermets

Ceramics International, 2017
Abstract Ti(C, N)-based cermets were coated with TiAlN and TiAlN/CrAlN films by physical vapor deposition. The cross-sectional morphology was characterized by scanning electron microscopy (SEM), and the adhesive strength was evaluated by the scratch test. Cutting tests on the coated cermets were conducted on the different cutting conditions.

Modeling of reactively sputtered TiAlN films

Thin Solid Films, 1998
Abstract Multi-component nitride TiAlN films were deposited on high speed steel substrate through the reactive sputtering process. A model was successfully developed for simulating the deposition of TiAlN. By following this model the deposition rate and nitride coverage fraction at various nitrogen rates and sticking coefficient of species were ...

Elastic stresses and microstructure of TiAlN coatings

Inorganic Materials: Applied Research, 2017
By X-ray diffraction and transmission diffraction electron microscopy methods, the phase composition, macro- and microstresses, and microstructure in a Ti1–x Al x N coating and a substrate were investigated. The coatings were deposited by magnetron sputtering of a Ti–Al target in an Ar +

Wettability of TiAlN films by molten aluminum

Thin Solid Films, 2006
Abstract In this study, we made an attempt to measure the wettability of the TiAlN films by molten Al at temperatures between 1073 K and 1273 K using an improved sessile drop method. The true contact angles cannot be obtained for the films deposited on the stainless steel and tungsten substrates due to considerable interdiffusion or reaction between ...

Temporal evolution of oxygen chemisorption on TiAlN

Applied Surface Science, 2014
Abstract The temporal evolution of the surface chemistry of cubic TiAlN at 1 × 10−3 mPa oxygen partial pressure and 300 K was analysed by means of X-ray photoelectron spectroscopy and by ab initio molecular dynamics simulations. Both the experimental and theoretical data imply that Ti and not Al determines the oxygen chemisorption process ...

Multilayer TiAlN coatings with composition gradient

Surface and Coatings Technology, 2002
Abstract The fuzzy-logic process control system has been adapted to the unbalanced magnetron reactive sputter deposition of Ti1−xAlxN coatings. This made possible the dynamic control of the deposition rate, chemical composition and structure of the coatings and provided stable working conditions inside the hysteresis loop of the reactive sputtering ...

Tribological properties of TiAlN‐coated cermets

Rare Metals, 2009
Abstract Ti(C,N)‐based cermets were coated with TiAlN using multi‐arc ion plating technology. Sliding wear tests were performed on the coated cermets. The microstructure and morphologies of the coated cermets before and after friction and wear tests were characterized.

High-temperature tribological characterization of commercial TiAlN coatings

Journal of Physics: Condensed Matter, 2006
This study was performed with the aim of evaluating the relative tribological behaviour at high temperature of (Ti(1-x)Al(x))N coatings commercially deposited on WC inserts. The (Ti(1-x)Al(x))N multilayered, nanostructured and single-layer coatings, which contained different Ti/Al atomic ratios varying from 7/3 to 2/3 respectively, were deposited by ...

Hot corrosion behavior of TiAlN single-layer and thick Ti/TiAlN multilayer coatings at 700 °C

Journal of Vacuum Science & Technology A
Thick Ti/TiAlN multilayer coatings consisted of the periodic introduction of Ti layers into TiAlN layers were prepared onto TC4 titanium alloy substrates by arc ion plating. The results indicated that the thick corrosion product layer, which consisted primarily of Na2Ti9O19 and Al2O3, formed on the surface of the TiAlN single-layer coating in localized
