Insert with tabs and damped products and methods of making the same

Abstract

One embodiment includes an insert including a body portion; a plurality of tabs extending from the body portion, wherein the tabs are tapered; and wherein the insert is constructed and arranged to provide damping.

1 . An insert comprising:
 a body portion;   a plurality of tabs extending from the body portion, wherein the tabs are tapered; and   wherein the insert is constructed and arranged to provide damping.   
     
     
         2 . An insert as set forth in  claim 1  wherein the body portion has an annular portion comprising an inner edge and an outer edge; and wherein the plurality of tabs extend from at least one of the inner edge or the outer edge of the annular portion. 
     
     
         3 . An insert as set forth in  claim 1  wherein the body portion comprises steel. 
     
     
         4 . An insert as set forth in  claim 1  wherein the tabs have a triangular shape. 
     
     
         5 . An insert as set forth in  claim 1  further comprising a coating over at least a portion of the insert. 
     
     
         6 . An insert as set forth in  claim 5  wherein the coating is about 1 μm to about 400 μm thick. 
     
     
         7 . An insert as set forth in  claim 5  wherein the coating comprises at least one of silica, alumina, graphite with clay, silicon carbide, silicon nitride, cordierite (magnesium-iron-aluminum silicate), mullite (aluminum silicate), zirconia (zirconium oxide), phyllosilicates, other high-temperature-resistant particles, clay, Al 2 O 3 , SiO 2 , an organic binder, an inorganic binder, a lignosulfonate binder, a calcium lignosulfonate binder, cristobalite (SiO 2 ), a fiber, a ceramic fiber, a mineral fiber, quartz, an epoxy resin, a phosphoric acid binding agent, calcium aluminates, sodium silicates, wood flour, non-refractory polymeric materials, ceramics, composites, wood, or a liquid dispersed mixture of alumina-silicate-based, organically bonded refractory mix. 
     
     
         8 . An insert as set forth in  claim 1  further comprising a layer comprising particles or fibers over at least a portion of the insert.
