20130240373 | PROCESS FOR REMOVING A COATING FROM WORKPIECES - The invention relates to a process for electrochemically removing a coating from coated workpieces by means of a voltage applied in an electrolyte bath between the workpiece and a counter-electrode. According to the invention, a rising voltage profile is selected during the coating removal process. This has the effect that the voltage applied at the start is low, and therefore the workpieces are not damaged, but nevertheless the rise in the voltage prevents the coating removal process taking an uneconomically long time. | 09-19-2013 |
20140027305 | ULTRASONIC DISRUPTION OF AN ANODOTIC FILM DURING ELECTROPOLISHING OF MEDICAL IMPLANTS - A method of electropolishing a medical implant is provided. During the electropolishing, an anodotic film forms around surfaces of the implant. Two or more ultrasonic transducers are oriented around the implant and are activated to disrupt the anodotic film. The ultrasonic transducers are activated only during a portion of the electropolishing process to allow the anodotic film to at least partially reform. | 01-30-2014 |
