Summary

Production methods and material compositions for sintered friction disc production by powder metallurgical technique that are used in friction units of automotive engineering, various vehicles and machinery.

Description

Friction disc manufacture consists in furnacing in a free state on steel surfaces with plating of powdery multi-component formulation followed by pressing out oil-offtake undercut groove profile and heat fixing of discs. Change in process variables makes it possible to produce sintered friction disks based on cuprum as well as on iron with adequate tribotechnical characteristics.
