This paper discusses the different types of rolls used in paper machines, the functions and performance required of them, and recent improvements achieved with the aid of thermal spray coatings. It presents examples showing how metal and ceramic coatings applied by HVOF and plasma spraying have reduced operating expenses and extended roll life by stabilizing and improving various surface properties.
