Electrochemical and Corrosion Behavior of Nanocrystalline TiNi-Based Alloys and Composite

摘要: In this work TiNi-based nanocrystalline alloys and composite were produced by mechanical alloying process with subsequent annealing at 750 ◦C for 0.5 h. Mechanical was performed in a SPEX 8000 Mixer Mill. TiNi alloy chemically modi ed Ag elemental powder. Silver content equaled 5 wt%. X-ray di raction analyses revealed formation of main phase after annealing. Additionally, two minor phases Ti2Ni TiNi3 detected unmodi alloy. Crystallites obtained powders nanosized. Corrosion electrochemical measurements 6 M KOH solution. All synthesized materials used as negative electrode Ni-MHx batteries. addition positively ects on stability discharge capacity during charge/discharge tests.
