Abstract
Aluminum matrix composites (AMCs) are difficult to machine conventionally. Pulsed Electrochemical Machining (PECM) is an alternative method to machine AMCs. Metals can be machined without contact, independent of material hardness and without mechanical or thermal impact. During the process no tool wear occurs. The AMCs consist of an aluminum matrix, which is easily to machine with PECM, and SiC-particles, which cannot be dissolved during the electrochemical machining process applying neutral electrolytes. This combination leads to a special behavior of dissolution and anodization. In this study, the influence on the surface layer, caused by Pulsed Electrochemical Machining of AMCs, is analyzed.
