Abstract
Results of experimental studies concerning the influence of permanent magnetic field on wear of lubricated sliding contact operating at short stroke and high frequency are presented. It was found that horizontal magnetic is affecting performance of the contact. The jagged delamination regions produced in the presence of a magnetic field can be regarded as easily undergoing oxidisation because oxygen is readily adsorbed there. Magnetic field is likely to intensify the abrasive action by wear particles and mitigate wear of the plate specimen. It is postulated that all these effects are caused by the influence of magnetic field on the electrical charge of the worn surface created on Si3N4 ball.
Highlights
The influence of magnetic field on sliding contact performance is an important problem especially nowadays with the advent of mechano-electrical devices such as, for example, magnetic data storage hard discs [1]

Summary
The influence of magnetic field on sliding contact performance is an important problem especially nowadays with the advent of mechano-electrical devices such as, for example, magnetic data storage hard discs [1]. Magnetic field influences the plasticity of a ferromagnetic material according to Muju and Ghosh [3] It has been found by several researchers that the magnetic field changes the microhardness and mechanical properties of materials. Kumagai et al [8, 9] and some other researchers reached the conclusion that a magnetic field affects the process by reducing the wear activation energy. They expressed the view that magnetisation promoted generation of the minute particles and oxidisation of the wear debris because the wear products were attracted by magnetic force and were held in the contact area. Arrangements of magnets creating magnetic field perpendicular to the sliding direction was denoted 0° and was exclusively used in the experiments reported in this article
