20.500.12556/DKUM-92236 Development of a new AuCuZnGe alloy and determination of its corrosion properties In this paper, we present the idea and development of a new gold-copper-zinc-germanium (AuCuZnGe) alloy, which is related to the method of production and research of its key properties, so that the new Au alloy could be used for jewelry production and in dental technology. The research design was associated with the determination of appropriate chemical composition, manufacturing technology, and performing the characterization. Melting and casting technologies were used to cast the AuCuZnGe alloy while rolling was used to prepare the cylinders and cutting to make square plates with a = 10 mm and thickness of 1 mm. Such plates were provided for corrosion testing. Observation of the plate0 s microstructure was performed with Scanning Electron Microscopy (SEM) equipped by Energy-Dispersive X-ray spectrometry (EDS) and X-ray diffraction (XRD). Corrosion testing involved performing the following measurements: Polarization, the open circuit potentials, and linear polarization resistance. Based on the SEM, EDS, XRD, and results of corrosion testing it can be concluded that the new AuCuZnGe alloy possesses high corrosion stability and can be classified as a high noble alloy. gold alloy germanium production characterization corrosion properties zlitine zlata germanij proizvodnja karakterizacija korozijske lastnosti true false true MDPI AG Angleški jezik Slovenski jezik https://www.mdpi.com/journal/metals © 2022 by the authors Članek v reviji 2025-03-24 12:01:00 2025-03-24 12:01:00 2025-03-25 03:09:41 0000-00-00 00:00:00 2022 0 0 Str. 1-11 iss. 8 (1284 Spec. iss.)
