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 ...

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.

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.

Tribological properties of carbonized photoresist

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1991
AISI 52100 bearing steel samples were coated with 0.3 to 0.8 μ.m AZ 5210 photoresist by conventional spinning techniques. Ion bombardment with N, Al, and P ions in the dose range of 1016 cm−2 and at an energy of 200 keV was conducted to carbonize the resist and to mix the carbonlike layer with the steel substrate.

Tribological properties of ormosil coatings

Journal of Sol-Gel Science and Technology, 1996
Transparent plastics are not scratch resistant. The damage leads to a loss of optical properties. Coatings prepared using either tetraethoxysilane or colloidal silica particles embedded in “glymo” is a way to avoid these disadvantages. Tribological experiments are carried out to better understand the surface modification due to a sliding friction.

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 and Mechanical Properties

1980
Publisher Summary This chapter explores the interactions between ion beams and metal surfaces that can lead to changes in mechanical properties. Tribology is a study of friction, lubrication, and wear of engineering surfaces with a view to understanding surface interactions in detail and prescribing improvements in given applications.

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.
