Surface treatment methods for Ni-based metallic glasses are provided that promote passivation and decrease the amount of Ni released when the Ni-based metallic glass is exposed to a saline containing environment. L'invention concerne des procédés de traitement de surface pour verres métalliques à base de Ni qui favorisent la passivation et diminuent la quantité de Ni libérée lorsque le verre métallique à base de Ni est exposé à un environnement contenant une solution saline.
