Sintered Copper-Based Powder Friction Material Filled with Fullerene-Like Glass Carbon

Resumo

Existing compositions of sintered copper-based powder friction materials have been analyzed. It has been indicated that these materials, which operate under lubricating conditions, usually contain fine pencil-type or coarse casting graphite as an antiseize additive. As a friction additive, oxide and carbide powders and other high-melting materials are used. In this work, the results of investigations of tribotechnical properties of the sintered powder friction material based on copper filled with glass carbon are given. It is shown that its use provides an increase in the friction coefficient of the material with a decrease in wear over the period of its operation.
