Tribological Properties of Epoxy+Silica Hybrid Materials
Journal of Nanoscience and Nanotechnology, 2009Various amounts of nano size silica particles prepared by a sol-gel process were added to epoxy+ amine systems. We have investigated tribological properties including friction and sliding wear resistance of hybrids so obtained, and also relationships between different tribological properties and surface topography.

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

Tribological Properties of Glass‐Ceramics
Journal of the American Ceramic Society, 1984Tribological properties of five glass‐ceramics are reported. The materials were tested unlubricated against themselves. Testing was performed using a simulated inertial sample dynamometer. Sliding speeds were between 0.5 and 1.8 m /S with an applied load of 225 N. Average friction coefficients were in the range 0.07 to 0.5.

Tribological properties of titanium alloys
Wear, 1991Abstract Titanium is often the most cost-effective corrosion-resistant material for applications in the chemical process industry that involve resistance to halides. Unfortunately, there are usually some components in these systems that involve relative sliding-titanium tribosystems — e.g. bolts and nuts, valves, piping connections, etc.

Tribological properties of grease modifications
2019The article assesses the efficiency of modification of greases with nanosized polytitanate potassium. The studies were carried out on a four-ball friction machine. The results of tribological tests of experimental lubricating compositions prepared using different concentrations of potassium polytitanate were obtained.

Tribological Properties of Solid Materials
1978Much of the material in the previous chapters has been concerned with the tribological properties of metals, and it is not necessary to reiterate it here. In particular, the effect of hardness on resistance to wear was mentioned frequently in Chapter 3 and the importance of oxide films was stressed in Section 3.5.

Tribological Properties of Metallic and Ceramic Coatings
2000The 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 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.

Tribological Properties of Ground Surfaces
World Tribology Congress III, Volume 1, 2005This paper presents the results of tribometric investigations of ground surfaces machined with different combinations of grinding regime. Though they belong to the same class of surface roughness, they show significant differences in tribological properties.
