Microstructure and Tribological Properties of DLC Coatings

Materials Research Proceedings, 2020
This paper presents the results of diamond-like carbon coatings deposited using the physical vapor deposition PVD process on 4H13 stainless steel samples. The properties were assessed by analyzing the coating microstructure, nanohardness, roughness and tribological tests.

Tribological Properties of Steels

2021
Abstract This chapter covers the friction and wear behaviors of carbon, alloy, and tool steels. It begins a review of commercially available shapes and forms. It then describes the metallurgy and microstructure of various designations and grades of each type of steel and explains how it affects their performance in adhesive and abrasive ...

Tribological properties of PTFE-filled PMIA

Journal of Applied Polymer Science, 1999
The polytetrafluoroethylene-filled (PTFE) poly(m-phenylene isophalamide) (PMIA) composite blocks are prepared by compression molding. The friction and wear of PTFE-filled PMIA are investigated on a block-on-ring machine by running the PMIA composite block against plain carbon steel (AISI 1045 steel ring).

Wetting and Tribological Properties of Ionic Liquids

The Journal of Physical Chemistry B, 2014
A phenomenological study of the surface-wetting and tribological properties of various ionic liquids was conducted using molecular dynamics simulations. The surface-wetting capabilities of the liquids were studied by simulating the morphological transformation of an isolated liquid drop in vacuum to its equilibrium state on solid surface.

Preparation and tribological properties of polyetheretherketone composites

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2010
AbstractPolyetheretherketone (PEEK) is a thermoplastic engineering plastic with excellent mechanical properties. In this article, PEEK and its composites filled with ultrahigh‐molecular‐weight polyethylene (UHMWPE) were prepared by vacuum hot‐pressing method.

Tribological properties of nanostripe surface structures—a design concept for improving tribological properties

Journal of Physics D: Applied Physics, 2010
The tribological properties of nanostripe surface structures were investigated using a pin-on-plate tribometer in order to propose a design concept for improving the tribological properties. The authors used four kinds of nanostripe structures consisting of different combinations of materials (Fe–Au, C–SiC, Al–Al2O3 and Al–Pt) fabricated by a process ...

Tribological properties of sulfur-implanted steel

Surface and Coatings Technology, 2004
Abstract The tribological properties of a low-alloy steel surface treated by sulfur ion implantation (concentration range 1–30 at.%) have been tested under boundary lubrication conditions and compared with untreated steel. Pin-on-disc wear tests, carried out at constant load and speed, showed that sulfur implantation of the discs had a pronounced ...

Tribological properties of 3-alkylthietanes

Petroleum Chemistry, 2008
Antiwear and extreme-pressure properties of 3-alkyl substituted thietanes (3-butyl-and 3-hexylthietane) taken as an admixture to vaseline oil were examined. A comparison of these properties with those of dibutyl sulfide and didodecyl sulfides, as well as dibutyl and didodecyl disulfides, showed that, although 3-alkylthietanes do not exhibit wear ...

Tribological Properties of Metallic and Ceramic Coatings

2000
The physical and chemical phenomena that govern both the friction and wear in moving contacts take place at the surfaces of the solids in relative motion. Usually, the interaction mechanisms at the outermost surfaces are the most crucial for tribological performance.

Mechanical properties of tribologically modified nanolayers

Tribotest, 2004
AbstractWear in modern mechanical systems is characterised by ultra‐low wear rates in the range of a few nanometres per hour. Both the surfaces of the materials involved and their volumes undergo modification as regards morphology, crystalline arrangement, and chemical composition.
