ABSTRACT:
A coating comprising a non-porous textured corrosion resistant and abrasion resistant base layer of metal is applied by a thermal flame spray process using a high-velocity oxy-fuel, and a top coating of a continuous film of fluoropolymer is used to enhance and protect the surface bare metal on industrial rollers in a multitude of industrial environments that are corrosive, abrasive or otherwise have elements present which tend to stick to the roller surface. The corresponding method comprises the steps of providing a body member having a relatively soft and corrodible metal first layer, applying a middle metal layer to the first layer by a high-velocity oxy-fuel type metal thermal spray process, applying an outer layer comprising a fluoropolymer coating over said middle layer to provide a non-sticking characteristic to the coating; and heating said outer layer to a level above the curing temperature of the fluoropolymer so as to bond the fluoropolymer to said middle layer.
