Tribological properties of 3-alkylthietanes
Petroleum Chemistry, 2008Antiwear 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, 1992Abstract 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, 2015Limonene 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, 1996Transparent 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 carbonized photoresist
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1991AISI 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 and Mechanical Properties
1980Publisher 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.

Tribological properties of quasicrystalline coatings
Journal of Materials Research, 1993Coatings of three different compositions (Al65Cu20Fe15, Al64Cu18Fe8Cr8, and Al67Cu9Fe10.5Cr10.5Si3) were realized by various thermal deposition techniques. They were studied in the as-deposited state and after annealing. In view of potential applications, these quasicrystalline coatings were examined from the point of view of tribology: friction and ...

Anisotropic tribological properties of SiC
Wear, 1982Abstract The anisotropic friction, deformation and fracture behavior of singlecrystal SiC surfaces were investigated in two categories. The first is that in which friction and wear of SiC arises primarily from adhesion between sliding solid surfaces in contact and the second is where friction and wear of SiC occur as a result of the surface sliding ...
