Tribological characteristics of MoSi2/SiC nanocomposites

Nanostructured Materials, 1995
The tribological behavior of surfaces depends on a number of factors including hardness, elasticity, fracture toughness, adhesion and oxidation rate. Many of these are determined unambiguously by the composition and microstructure. The ultimate way to modify the microstructure is a refinement of the grain size down to the nanometric scale. This results

Tribological Characteristics Modification of Magnetorheological Fluid

Journal of Tribology, 2011
Recently, research on the application of magnetorheological (MR) fluid in mechanical engineering has been widely expanded, while the performance of MR fluid in tribology has also been investigated. In this study, a modification of MR fluid, which is modified by adding certain additives, is attempted to improve tribological performance.

Tribological characteristics of hip joint endoprostheses

Journal of Friction and Wear, 2016
We have studied the friction pairs for a head–insert kinematic node of human hip endoprostheses and rabbit hip endoprostheses, both normal (intact) and with an osteoarthritis model, in conditions of dry friction and lubrication with biological medium.

Tribological Characteristics of Magnesium-based Nanocomposite

Materials Today: Proceedings, 2018
Abstract This paper investigates the tribological characteristics of magnesium (Mg) composites prepared by Disintegrated Melt Deposition (DMD). Attempt was made to identify the effect of filler types (i.e. nano-sized Alumina particulates, ∼50 nm) particles and Magnesium alloy on volumetric wear rate of magnesium composite. Experiment was done using a

Effect of Phosphomolybdates on the Tribological Characteristics of Lubricants

Journal of Friction and Wear, 2019
Abstract—The paper presents the results of studies on how the structure and physicochemical properties of polymer inorganic phosphorus-containing additives influence model lubricant bases (glycerol, liquid paraffin). Data of some tribotechnical tests are given.

Calculation of tribological characteristics of composite materials

Journal of Friction and Wear, 2007
We present the formulas for calculating the friction coefficient when fibrous composite material is rubbed against the homogeneous rigid material. The wear of the composite is taken into consideration in the calculation.

Tribological characteristics of needle bearings

1989
A Needle Bearing Test Rig has been constructed which allows the measurement of frictional torque, axial thrust, needle axial skew angle, and needle complement velocity for an applied radial load of up to 3500 N and a speed of up to 7000 rpm. Either shaft rotation or cup rotation can be accommodated.
