Abstract

The system described is a computer controlled electropolisher designed to generate the characteristic electropolishing curve and display the data in real time for a given set of conditions. The operator-to-system interface is achieved through menu-driven software which is designed to be user-friendly at all levels of operation. Computer programming skills are not required to operate the system. There are four main program available to the operator from the system main menu. These programs allow the operator to become familiar with the system and its capabilities, access the material and electrolyte libraries, perform an electropolishing experiment under computer control, and recall data from the system data base for analysis, comparison, and graphic presentation.
