Characteristics of Mg2-xTixNi1-yCuy-H-2 (0 < x < 2, 0 < y < 1) alloys

The Mg2-xTixNi1-yCuy(0<x<2, 0<y<1) alloys have been successfully synthesize d by the diffusion method (DM). We have investigated the gas-solid phase re actions of the alloys-Ii, system with and without the treatment of F-soluti on. A study of the hydrogen desorption process was also carried out. The re sults show that the main phase of the alloys is an Mg2Ni structure. The gas -solid phase reaction can occur without detailed surface treatment and acti vation. A study on the anti-corrosion properties in alkaline solution of Mg 2-xTixNi1-yCuy(0<x<2, 0<y<1) alloys electrodes has been done. The results s how that the addition of Ti improves anti-corrosion properties, while addit ions of Cu do not improve these properties. (C) 1999 Published by Elsevier Science S.A. All rights reserved.
