| Abstract: | 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. |
