Effect of preparation conditions on relative elongation of nickel foam.

The effect of preparation conditions on the relative elongation of nickel foams prepared by electrodeposition technology has been studied. The relative elongation is hardly influenced by sintering in NH₃ decomposition atmosphere at 980°C for 40 min, by burning in air at 600°C for 4 min beforehand, or by lowering the sintering temperature to 850°C. With regard to conductive treatment, the relative elongation is significantly higher for chemically plated Ni than for coating by graphite base conductive colloid. [ABSTRACT FROM AUTHOR]
