Application of Wear Resistant Coating Technology on Coating Blade

Article Preview

Abstract:

Coating blade wears seriously in paper coating process. Wear mechanism was analyzed in this article. A new technology of surface coating process was introduced to increase the hardness of the edge of coating blade and thus to prolong its service life. Surface coating preparing process on blade was studied and metal-ceramic compound coating prepared successfully on the edge of coating blade with AT13 (Al2O3+13%TiO2) wear resistant material by plasma spraying process. NiCrAl alloy powder was used as under coat material. Microstructure of the coating is dense. The coating bonds well with the matrix and have high hardness. Results of grain-abrasion testing show that wear-resisting property of the metal/ceramic compound coating is about 7-8 times as that of steel blade.
