CORROSION ESTIMATION KIT OF BIODEGRADABLE MAGNESIUM ALLOYS AND CORROSION ESTIMATION METHOD OF BIODEGRADABLE MAGNESIUM ALLOYS USED THEREOF

摘要

PURPOSE: A corrosion evaluation kit of a biodegradable magnesium alloy and corrosion evaluation method of the biodegradable magnesium alloy using the same are provided to easily implant a corrosion evaluation kit in vivo by using two electrodes and minimizing a size of the overall corrosion evaluation kit. CONSTITUTION: A corrosion evaluation kit of a biodegradable magnesium alloy comprises a specimen(10), an auxiliary electrode(20), a fixture(30), and an impedance analyzer. The auxiliary electrode is installed by being spaced from the specimen. The fixture fixes the specimen and auxiliary electrode. A specimen wire(41) connected to the specimen and auxiliary electrode wire(42) connected to the auxiliary electrode penetrate the fixture and connect to the impedance analyzer. The specimen is one of a biodegradable magnesium alloy or magnesium and the auxiliary electrode is a titanium alloy or platinum.
