Abstract
A elastomer-covered roller (10) is provided with an improved bond coating for bonding the elastomeric cover (14) to the core (11). At least one layer of material (15) is thermally sprayed on the core to form a rough surface having a roughness from 400 microinches R.sub.a to 2000 microinches R.sub.a or greater. In a further improvement a denser, less porous layer (17) may be applied next to the core to protect the core from corrosion, followed by a less dense layer (19) applied to the first layer and having a similarly rough surface (20) for good mechanical bonding.
