There are certain systems in which the primary function of sliding contacts is not the transmission of motion or work. For example, the purpose of a sliding electrical contact is to provide a low resistance electrical path between two bodies in relative motion. The contact between the magnetic head and a floppy disk or a video cassette recorder tape is

Abstract This article provides a broad overview of sliding and adhesive wear, its processes, and its control, with special attention to three general classes of materials: metals, ceramics, and polymers. It discusses the ways in which materials can be damaged and removed during sliding contact.

Prediction of wear in a sliding system
Tribology, 1968Abstract In previous publications, the author and his co-workers have presented two models concerning wear prediction in sliding systems. The first model, the zero-wear model, enables one to predict analytically the amount of sliding required to produce wear of the order of the surface finish.

Silicon segregation in sliding wear
Wear, 1983Abstract Friction experiments were conducted on a couple consisting of an Fe-Ni pin sliding against a tool steel disk. The Fe-Ni pin contained a small amount of silicon (0.18%). In a mild vacuum environment (0.1 mmHg at 10% relative humidity) at loads below a critical value (13.0 N, at a sliding speed of 0.22 m s −1 ), silicon segregation to the pin ...

SIMULATION OF SLIDING BEARING WEAR
Spravochnik. Inzhenernyi zhurnalBased on the Mechanical Engineering Research Institute of the Russian Academy of Sciences method, a modeling apparatus was developed, using which, based on the results of laboratory bench and field tests, a material F40K20M1.5 was proposed for a sliding bearing, with the replacement of turbine oil 22 with water.

Wear processes in sliding systems
Wear, 1984Abstract A sequence of events involved in sliding wear is outlined. Local contacts cause large plastic strains in either or both solid components. The plastic deformation changes the near-surface microstructure in ways which make the material unstable to local shear.

A model of sliding wear of ceramics
Journal of Materials Engineering, 1990A fracture mechanics analysis shows that a subsurface crack, acted upon by the stress field associated with an asperity contact, will extend out of its plane in a direction towards the surface of the wear piece. It is suggested that this effect is the first stage of debris formation in sliding wear of ceramics.

Friction and Wear of Sliding Bearings
2017AbstractBearings are usually provided where a specific spatial relationship (alignment) must be maintained between the parts or where a force is to be transmitted from one part to the other. This article introduces the general types and configuration of sliding bearings, bearing materials, and the practical aspects and solutions in the friction ...

The Mapping of Metallic Sliding Wear
Proceedings of the Institution of Mechanical Engineers, Part C: Mechanical Engineering Science, 1988Mechanisms of machining (abrasive), fatigue and transfer wear are reviewed in the context of the interfacial shear stress (adhesive) and surface roughness (deformation) conditions in which they occur. In the first part it is shown how model predictions of surface flow, friction and wear may be mapped on to a field with surface shear strength and ...

Predictive Models for Sliding Wear
1988Wear is defined as “damage to a solid surface, generally involving progressive loss of material due to relative motion between that surface and a contacting substance or substances” [1]. Examination of worn machine elements indicates that the wear process is rather complex and can occur by various mechanisms [2].
