Abstract
An aperture plate for an ink jet printer of the continuous stream type is made corrosion resistant to the ink for long printer operating times. The aperture plate is made corrosion resistant by ion implantation, preferably of chromium ions by an ion beam implanting device. The walls of the aperture plate nozzles are substantially uniformly implanted by rotating and concurrently angling the aperture plate relative to the ion beam direction. The ion beam density and ion potential are regulated to predetermined ranges to assure effective corrosion protection while preventing overheating which will warp or embrittle the aperture plate.
