A elastomer-covered roller ( ) is provided with an improved bond coating for bonding the elastomeric cover ( ) to the core ( ). At least one layer of material ( ) is thermally sprayed on the core ( ) to form a rough surface having a roughness from 400 microinches R to 2000 microinches R or greater. At least one layer ( ) is either sufficiently permeable to divert bond-degrading fluids away from the bond line ( ) or is impermeable to bond-degrading fluids.

Elastomer-covered roller having a thermally sprayed permeable bonding material

A elastomer-covered roller ( ) is provided with an improved bond coating for bonding the elastomeric cover ( ) to the core ( ). At least one layer of material ( ) is thermally sprayed on the core to form a rough surface having a roughness from 400 microinches R to 2000 microinches R or greater. In a further improvement a denser, less porous layer ( ) may be applied next to the core to protect the core from corrosion, followed by a less dense layer ( ) applied to the first layer and having a similarly rough surface ( ) for good mechanical bonding.
