Paper Abstract

Laser welding of dental alloys is much more easy and faster than the soldering procedure of the same materials. Requirements for application of such junction are their stability and biocompatibility. Last is strong connected to the electrochemical, means corrosion, stability. Corrosion stability can be assessed by current (I) vs. potential (E) curves. The problem is the preparation of specimens and also the interpretation of the shape of I vs. E curves. The aim of this work is to demonstrate a new cell configuration for a fast and easy measurement routine. In this way it is possible to assess the electrochemical behavior direct and without preparation of separate specimens. The application of such system is possible in each technical lab and so it should be possible to reduce failures during the selection and combination of materials.
