Influence of Temperature and Temperature Prehistory on Frictional Characteristics of Metal Friction Pairs

Journal of Friction and Wear, 2020
The temperature effect on the frictional characteristics of a silver-silver friction pair was experimentally studied. These characteristics are as follows: Amontons’ and Coulomb’s friction coefficients and specific friction force parameters. The applicability of the Coulomb’s friction law to the description of the friction force dependence on the ...

Device for Tribotechnical Tests of Friction Pairs

Journal of Friction and Wear, 2020
Abstract—This article sets out the basic principles and approaches to modernizing a friction testing machine. The advantages and disadvantages of existing devices for tribotechnical testing of friction pairs are investigated. It is noted that friction machines manufactured by OAO TOChPRIBOR, Ivanovo, including the 2070 SMT-1 friction testing machine ...

Friction brakes in railway vehicles – the phenomenon of friction pairs contact

Developments in Mechanical Engineering, 2022
Rail vehicle brakes have evolved in recent years by applying the first results of research on new friction materials that replace cast iron. The article dis-cusses the phenomena occurring in the friction pairs of rail vehicle brakes in rela-tion to the current issues related to the implementation of composite materials for commercial applications.

Friction Coefficient Model of Friction Pair Composed of Automotive Brake Materials

Volume 4A: Dynamics, Vibration, and Control, 2014
The friction experiments are conducted on a pin-on-disc friction material testing machine. The sliding velocity, pressure, temperature and friction coefficient are measured. The effects of brake temperature, brake pressure and braking speed on the friction coefficient are examined.

Frictional behaviour of timber-concrete contact pairs

Construction and Building Materials, 2020
Abstract While friction plays an important role in many timber-concrete composite structures, it has been studied only to a limited extent and current knowledge is not comprehensive enough for rigorous modelling of e.g. timber-concrete connections.

A frictional pair composed of sintered materials

Soviet Powder Metallurgy and Metal Ceramics, 1973
1. It is advantageous to formulate frictional pairs both elements of which are made in sintered materials. With this approach, it is possible to make fuller use of the advantages of the powder-metallurgy technique and of the individual characteristics of each material in “designing” suitable frictional pairs for any given type of service. 2.

Experimental Research of Scuffing of Friction Pair

Applied Mechanics and Materials, 2014
The scuffing of friction pair is a common phenomenon in conditions of high speed and pressure. It was researched on scuffing characteristics in this paper. By using UMT-3 friction and wear tester, the friction and wear characteristics of slipper pair material in hydraulic component were investigated, and the friction coeficient-speed curves in the ...

Friction in transition metal-refractory compound pairs

Soviet Powder Metallurgy and Metal Ceramics, 1973
1. The friction process in a metal-refractory compound pair is accompanied by intense adhesion of the metal to the mating surface, which leads to cold welding between the transferred metal and the metal specimen and to particles of the harder refractory compound being torn out. 2.
