Studies on the influence of Be content on the corrosion behavior and mechanical properties of Ni-25Cr-10Mo alloys.
The influence of Be content on the corrosion behavior and strength of dental alloys was examined using experimental Ni-25Cr-10Mo-xBe alloys with graduated Be contents of 0, 0.6, 1.1, 1.6, and 2.1 wt.%. It became evident that the corrosion resistance is reduced even by a 0.6 wt.% Be content. Strength increases by 51% with increasing Be content, while ductility is reduced by 84%. The results revealed that, from the stand-point of corrosion resistance, Be-free Ni-Cr-Mo alloys should be preferred in clinical use.
