PURPOSE: To produce a high density sintered Zn-Ni alloy suitable for electric material and plating material.
CONSTITUTION: A powder mixture of Zn powder and 5-50wt.% Ni powder is subjected to pressure sintering at 200-600°C at ≥5Kg/cm2 pressure, by which a high density sintered Zn-Ni alloy of 5-50wt.% Ni content can be obtained. By this method, the high density sintered Zn-Ni alloy having high Ni content can be easily produced. Moreover, the control of the composition is facilitated and the production of the high density sintered Zn-Ni alloys suitable for various purposes is made possible, and further, Ni content in a plating bath can be precisely controlled when this alloy is used for plating material, and as a result, a high grade plating film can be formed.
