Studies on the influence of BE content on the corrosion behavior and mechanical properties of Ni-25Cr-10Mo alloys

Abstract 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 standpoint of corrosion resistance, Be-free NiCrMo alloys should be preferred in clinical use.
