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

Tribological characteristics of SiN/sub x/ films

IEEE Transactions on Magnetics, 1999
The tribological performance and chemical compositions of thick (75 nm-120 nm) amorphous SiN/sub x/ films are studied with CSS testers and XPS. A high-speed H/D contact program is used to provide intermittent head/disc contacts. Films with high Si/N ratio (1.25) and high oxygen concentration (22%) have the best durability.

Tribological characteristics of some environmentally friendly lubricants

Wear, 2001
Abstract The lubricating properties of a new class of esters were studied using a pin on disc tribometer. These molecules are peresters (full esterified esters) of sugars. These peresters are compared to a set of classical esters: esters of pentaerythritol, of trimethylol propane or glycerol.

Tribological characteristics of detonation sprayed alumina coatings

Materials Today: Proceedings, 2020
Abstract Thermally sprayed aluminium oxide coatings are extensively used for functional applications where high wear resistance is of high significance. Among the various thermal spray coating methods, D-gun (Detonation gun) coating technology produces alumina coatings of excellent quality.

Tribological Characteristics of Rubber-Based Friction Materials

Tribology Letters, 2010
This article deals with the rubber-based friction materials (RBFMs) which can be used in brake system. The physico-mechanical and tribological properties of a series of fiber filled RBFMs containing steel wool and aramid pulp at different concentrations along with a fiber-free reference material were characterized.

Tribological characteristics of ion nitrided sintered steels

Surface and Coatings Technology, 1999
We have investigated the microstructure and wear behavior of ion nitrided and nitrocarburized sintered steels. The specimens were steamed at 520°C after sintering at 1120°C to improve the density. Up to 0.1 mm beneath the surface the ferrite phase was developed by decarburization during steaming. A decrease in hardness at the near surface resulted from

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.

Tribological characteristics of molybdate esters

This work explores the effect of the alkyl group of molybdenum ester additives on antiwear. The additives were synthesized by the reaction of diethanolamine, molybdenum salt and various fatty acids. The derived additive was then mixed with base oil and tested for wear property. The synthesized molybdate ester contained molybdenum about 2 wt%.

Tribological characteristics of nickel based composite coatings

Wear, 2003
Abstract Nickel composite coatings have been prepared on mild steel substrates by sediment electro-co-deposition (SECD) technique. Silicon nitride, fly ash and calcium fluoride are used as the reinforcements. Metallographic studies, microhardness, friction and wear tests under various loads and sliding speeds have been carried out on these coatings ...
