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 Cast Irons
2021Abstract This chapter covers the friction and wear behaviors of cast irons. It describes the microstructure and metallurgy of gray, white, malleable, and ductile cast irons, their respective tensile properties, and their suitability for applications involving friction, various types of erosion, and adhesive and abrasive wear.

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 a binderless carbide
Wear, 1999The tribological properties of a binderless carbide (BL) have been evaluated in abrasion and sliding wear tests. Conventional cemented carbides and ceramics were used as reference materials. The worn surfaces were studied with scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX).

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 ...

Drilling fluids can be clay-based, oil-based, and polymer-based. Polymer drilling fluids reduce friction in the drill string. Polymer drilling fluids also prevent jamming of the drilling tool and perform an anti-corrosion function. Friction is one of the key characteristics of drilling equipment wear. Reducing friction reduces metal wear, which in turn

Testing of Tribological Properties of ADI
2019This experimental work consists of testing of isothermally improved specimens for wear process without lubrication. In the first part investigated was tribological properties on tribometer pin on disc made produced from ADI. Tested was loss of length and loss of mass of pin for different increasing number of revolutions.

Tribological properties of PA66 nanocomposites
2012Nano- and micro- composites were prepared from a PA66 matrix with the addition of varying content of nanoclay, fullerene, polyhedral oligomeric silsesquioxane (POSS) and glass spheres. The composites’ scratch hardness was evaluated by using Pelletier’s model and results were correlated with their bulk mechanical properties.

Tribological Properties of Rubberlike Materials
1983Friction is reggarded as a fundamental energy-dissipative mechanism1,2 as a result of which surface degradation and wear occur. In the case of rubberlike materials, such a mechanism exhibits distinct viscoelastic properties, and it is common to distinguish between adhesional and hysteresis friction.
