Sintering was carried out in vacuum/argon atmosphere at low temperature in order to enhance surface electroactivity by an increase if the geometric area. The Ni-Co alloyng was obtained by mechanical synthesis, making use of the appropriated route. The final electrodes presented porosity of around 12% where the electrochemical tests presented increasing in the critical peak when compared with eletroplated flat samples.  aelectrochemistry  aMechanical alloying  aSintering  aWater electrolysis1 aCRNKOVIC, F.
