<p>An inkjet printhead (10) has at least one electrode, with exposed metal region (s) (16) of the electrode surface having a coating of inert metal, In use of the printhead, the inert metal coating functions to protect the underlying metal surface of the electrode, and in particular protects the electrode from corrosion to aqueous or other ion-containing inks. The invention is of particular benefit in piezoelectric printheads.</p> |
