Method for coating a substrate

A method for coating a substrate includes the steps of: forming a conductive coating layer on a surface of a substrate so as to form a semi-product; submerging a conductive sheet and the semi-product into an electrophoresis medium that includes charged colloid particles; and applying a voltage on th...

Zusammenfassung:A method for coating a substrate includes the steps of: forming a conductive coating layer on a surface of a substrate so as to form a semi-product; submerging a conductive sheet and the semi-product into an electrophoresis medium that includes charged colloid particles; and applying a voltage on the conductive sheet or the semi-product to form an electric field among the conductive sheet, the semi-product, and the electrophoresis medium, so that the colloid particles move along the electric field toward the semi-product and an electrophoretic covering layer formed by the charged colloid particles is thus deposited on the electrophoretic covering layer.
