Roll Coating for
Paper Mills
Ceramic and carbide roll coatings for Yankee dryers, suction rolls, press rolls and doctor blade hardware, plus metallized corrosion protection for wet-end components that live in warm chloride-bearing white water.
Components We Coat in Paper Mills
Yankee dryer coating for controlled crepe and sheet release
Suction roll shell coating and corrosion protection
Press roll and centre roll wear surfaces
Doctor blade holder and blade seat wear faces
Wet-end corrosion protection for headbox and white water parts
Dryer cylinder journal and bearing seat reclamation
Typical Outcome
Typical outcome: a coated Yankee surface runs a full production campaign between regrinds, and metallized wet-end steel resists chloride pitting.
Coating Processes Used
HVOF for dense tungsten carbide roll surfaces
Powder flame spray for chrome oxide ceramic roll faces
Twin wire arc spray for stainless and bronze suction roll shells
Wire flame spray (metallizing) of zinc and aluminium for wet-end steelwork
Coating Materials Specified
WC-Co-Cr for Yankee dryer and press roll wear faces
Chrome oxide (Cr2O3) ceramic for release and abrasion
316L stainless wire for suction roll and white water exposure
Aluminium bronze for suction roll shell reclamation
Zinc-aluminium 85/15 for wet-end corrosion barriers
