Analysis of a steel disk surface running in tandem with the metal–ceramic friction material MK-5 under the conditions of boundary friction of a hydromechanical transmission

Abstract

The development of metal–ceramic copper-based materials that operate under lubrication requires experience in operation under normal conditions, as well as with disruption of operation. The exclusion of a component or substitutions in the material composition is an important issue when taking into account that the component belongs to a group of hazardous substances that contain lead in MK-5 metal–ceramic copper-based friction materials.
