Functional Coating Materials for General Machinery
Wear / corrosion / insulation coatings
Melting point about 2038 °C; wear-, corrosion- and heat-resistant coatings with strong resistance to abrasive, adhesive and fibre wear, particle erosion and cavitation. Used on mechanical seals, slurry-pump pistons, hydro-turbine blades, valve heads and seats, guide rollers, friction plates, and for electrical insulation.
