Tribological Properties of TiN/Ag Nanocomposite Coatings

Abstract

Morphology, structure, and tribological behavior of magnetron co-sputtered TiN/Ag nanocomposite coatings deposited at 150°C with an Ag content in the range of 7-45 at.% were characterized. The coatings show a columnar structure with embedded Ag crystallites of 3-50 nm in diameter, where the columns are characterized by a layered structure with Ag-poor and Ag-rich layers. These layers originate from sample rotation during deposition, where the layer thickness increases with increasing Ag content. These Ag layers become continuous over a critical Ag content. At room temperature the friction coefficient is determined by the film structure, whereas friction and wear at high temperature depend on segregation of Ag to the surface.

Microstructure and tribological properties of NbN-Ag composite films by reactive magnetron sputtering

“…For instance, Mulligan et al [10] recently combined CrN with the noble metal Ag to produce CrN-Ag self-lubricating films and found that these films exhibit better friction and wear properties than the CrN matrix film. Similar results were also reported in other TMN-Me films such as TaNAg [11,12], CrAlN-Ag [13] and TiN-Ag [14]. In recent years, the NbN-Ag chameleon films were reported to extend the working temperature to 1000 • C [15].…”

“…However, the reactive sputtering process from Mo Targets using a lambda probe to control pO 2 is quite stable. [7] Fig. 2. shows the dependence of the O 2 partial pressure (pO 2 ) which is needed for a highly absorbing semitransparent MoO x film and the deposition rate on the target power density.…”

Nanocomposite Coatings: Preparation, Characterization, Properties, and Applications

“…For these coatings, PVD method includes the following: laser ablation [98], thermal evaporation [99], ion beam deposition [100], ion implantation [101,102], laser-assisted deposition [103], and atom beam cosputtering technique. In case of O/I nanocomposite coatings, Schild [104] has successfully fabricated the nanocomposite coating with organic matrix, by using the aerosol-assisted plasma deposition.…”
