The effect of microstructure on a beryllium bronze wear

Abstract

Tribological characteristics of beryllium copper were studied depending on its structural state according to the pin-on-disk scheme under the conditions of dry sliding friction. It is shown that, in the case of quenched samples, wear was realized by a corrosion-mechanical mechanism, i.e. there was oxidation of the friction surface with the subsequent separation of wear products in the form of ultrafine particles. The wear of the aged sample occurred by the separation of large wear particles as a result of the adhesive interaction of the sample with the counter body.
