Abstract

The results of experimental studies of the damping capacity of metal and polymer coatings are presented formed by methods of gas-flame spraying, deformation cladding with a flexible tool and galvanic deposition. The logarithmic damping decrement was chosen as a criterion for evaluating the damping capacity. It is established that polymer coatings based on PET-grade polyethylene terephthalate (TS 6-06-S199-86), formed by gas-flame spraying, and nickel-based metal coatings, obtained by galvanic deposition, contribute to an increase of damping capacity in 35...45 %. Thin coatings based on copper and babbitt, with a layer thickness of 4 μm, formed by deformation cladding with a flexible tool, slightly reduce the damping capacity, however, when applied to the working tooth profile of gears, an integrated spindle node of the console milling machine OSh F-32 helps reducing its noise by 1...5 decibels.
