METHOD FOR FORMING A PHOTOCATALYST COATING LAYER ON THE SURFACE OF A METAL FILTER THROUGH AN ARC ION PLATING METHOD

摘要

PURPOSE: A method for forming a photocatalyst coating layer is provided to manufacture a filter suitable for large area coating or mass production by forming a photocatalyst coating layer on the surface of a metal filter through an arc ion plating method.;CONSTITUTION: A foreign material on the surface of a metal material is removed. A photocatalyst coating layer is formed on the surface of the metal material through an arc ion plating method after the metal material is putted inside the vacuum chamber. The photocatalyst coating layer is formed by applying a negative bias voltage of 100-150V to a holder supporting the metal material and making arc discharge.;COPYRIGHT KIPO 2011
