Machines producing paper and cardboard comprises of many parts that are prone to high wear and corrosion problems such as rolls. Coatings are used in several types of rolls and cylinders components such as:
Center press rolls
Dryer cylinders
Calendar rolls
Traction rolls
Yankee cylinders
Anilox rolls
Corona rolls
Feeder / Draw / Pull rolls
Clutch Components
Coating materials used are iron and nickel-base alloys, nickel–chromium self-fluxing alloy, carbides, oxide, ceramics, and various multilayers, again depending on the application.
Generally, rolls are coated by NiCrBSi coatings flame sprayed, and others by WC–Co coatings HVOF sprayed.
