Damping Metallic Materials with a Nanostructured Coating

Abstract

Lathes are distinguished by high performance and increased noise levels. Reduction of this noise is achieved in different ways. Use of damping metallic materials is an effective way. Metal damping materials are distinguished from analogs (non-metallic materials) by high strength properties. Often non-metallic damping materials cannot replace steels and alloys due to low operating temperature and other physicomechanical properties. Steel damping properties are rarely investigated, and this limits the use of these alloys. Designers and engineers do not have information about damping properties of well-known steels. Properties of developed damping steels are investigated. Damping bushes of monolithic and bimetal structures are tested.
