PURPOSE: To improve abrasion resistance of tooth tip of a card clothing with easily practicable means, by applying titanium powder to tooth tip in nitrogen atmosphere and irradiating the powder with laser beam, thereby forming a titanium nitride layer on the surface of the booth tip.
CONSTITUTION: The tooth tip 4 of a metallic card clothing 1 is coated with titanium powder is nitrogen gas atmosphere and irradiated with laser beam 7. A titanium nitride layer 8 is formed on the surface of the tooth tip 4 by this process. The application of titanium powder may be carried out by mixing the powder with an organic binder, applying the mixture of the tooth tip and heating the applied mixture to remove the binder by evaporation, decomposition or combustion.
