Electrolytes for Sustainable Laser-Chemical Machining of Titanium, Stellite 21 and Tool Steel X110CrMoV8-2

Abstract:

Laser-chemical micro structuring offers a possibility to process particular metals nearly without any mechanical or thermal stress. The required electrolyte depends on the respective chemical composition of the specific metal. The presented results demonstrate the possibilities for laser-chemical machining of titanium, Stellite 21 and tool steel X110CrMoV82 for use in medical applications and micro tool manufacturing with respect to the engineering requirements. Furthermore, first results are shown depending on the identification of more environmentally friendly electrolytes to meet the everincreasing environmental and industrial standards.
