Tribological and Sensory Properties

2021
Eating, functionalized by mouth physiology, is performed through a series of processes which collectively helps in food ingestion, preparing the food for swallowing, ab-initio digestion, and food sensory perceptions. Sensory properties of food are typically defined by its texture, flavor, and color.

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).

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 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 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 ...

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.

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 COPNA resin

Wear, 1992
Abstract In this study, the effects of the addition of several solid lubricants on the hardness, bending strength, impact strength and tribological properties of COPNA (SK) resin were evaluated. The solid lubricants were polytetrafluoroethylene (PTFE), molybdenum disulphide (MoS 2 ) and graphite (GP). The results are summarized as follows. 1. (1)

Tribological Properties of Limonene Bisphosphonates

Tribology Letters, 2015
Limonene was chemically modified by reacting it with dialkyl phosphites of varying alkyl structures under inert atmosphere in the presence of free radical initiators. The reaction gave a mixture of mono- and di-adduct products and was optimized to produce only the di-adduct product limonene bisphosphonate by forcing both limonene double bonds to react ...

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.
