Abstract: A method and a product are provided for improving the resistance to abrasion of a load-carrying surface of a conveyor belt formed of a cord-reinforced elastomer material selected from the group consisting of natural and synthetic rubber, the belt being adapted for use for conveying particulate ore or other particulate material having abrasive properties. The method employed comprises cleaning the surface of the conveyor belt prior to coating the same with an abrasion resistant coating. The conveyor belt is characterized by a distribution of pores in the surface to be coated. A flexible coating of a polymer selected from the group consisting of polyolefins and polyester elastomers is flame sprayed in the molten state onto the conveyor belt surface using a flame spray torch. The flame of the torch is spaced from the conveyor surface to avoid contacting of the flame with the surface being coated. The coated conveyor belt is then cooled to provide a flexible polymer coating strongly bonded chemically to the surface and additionally mechanically bonded thereto by virtue of the coating material entering the pores of the surface of the belt and thereby mechanically locking the coating to the conveyor belt surface.
