- Abstract
Medical alloys are used in the medical field to create devices and implants due to their specific properties, such as biocompatibility, corrosion resistance, and suitable mechanical properties. The use of these alloys in modern medicine has revolutionized many procedures and treatments, enabling the creation of more durable and compatible implants with the human body. The choice of a specific type of alloy depends on the specific application and the necessary properties to ensure the long-term success of the implant or medical device. In this paper, possible detrimental effects caused by chemical and microstructural inhomogeneities of implants were studied. Three types of dental alloys often used in practice were investigated, namely: NiCrMoSiVCuFe, NiCrMoSiFeAlMgZn and CuAlNiFeMgZnSi. By correlation of SEM microscopy with the EDS data regarding the elemental compositions it results that there is a chemical inhomogeneity at the level of the investigated samples and structural inhomogeneity at the micron scale. These obtained data represent an essential step in understanding and improving implant performance and their impact on durability.
