INDUSTRIAL APPLICATIONS OF ADVANCED ELECTROCHEMICAL FINISHING TECHNIQUES

Abstract

ABSTRACT Faraday Technology, Inc. has developed electrochemical techniques for the edge and surface finishing of advanced materials, such as titanium alloys, stainless steels, and nickel based superalloys. This technology employs electrochemical metal removal under the influence of a bipolar, pulsed electric field to provide enhanced process control and excellent surface finishes. This process achieves high rates of metal removal in the presence of simple chemistries that are pH neutral, water based, non-toxic, and environmentally benign. This is in contrast to competing technologies that rely on electrolytes that are comprised of concentrated acids or ethylene glycol. This paper will present Faraday's recent development efforts in a wide variety of industries, including the semiconductor, automotive, and medical industries
