Abstract

The focus in this paper is directed toward to the investigation into hybrid metal-polymer-ceramic damping coatings. Sandwiched coating's layers have been manufactured by advanced technology based on combination of thermal flame spraying of foamy aluminum or its alloy and viscous-elastic polymeric (polyamide) layers, including 1-4 wt.% reinforcing additives of carbon nanotubes. Technological aspects of manufacturing are being discussed in terms of vibration damping properties and strength of the materials. The CNT-reinforced material is formed as a constrained-layer damping coating system (CLD) showing the greatest range over which damping have excellent energy absorbing/damping properties over bulk materials. Modal loss factors obtained at 60-80% partial-coverage of tested specimens was higher than that of maximum damping obtained in the case of 100% specimen coverage. FEM-based computer modeling was used to predict the damping of multilayer materials by a strain energy method. An effective damping design involves selecting a proper combination of coverage area, relative thickness and stiffness values of the CLD configuration. The coating could be recommended for applications in sliding and rolling bearing units, low-speed and light-weight gearing drives and other machine parts.
