摘要：
In connection with coatings combining low contact electrical resistance with good corrosion resistance, a comparison is made of the corrosion properties of nickel and nickel-boron coatings in a 1-mm HCl solution. The specimens were nickel bases with a galvanic nickel coating produced in a sulfate nickel plating bath and a nickel-boron (0. 1 wt. % B) galvanic coating produced in the same bath with the addition of 10 ml/liter of hydrazine borane. The steady potential of the nickel coating is always 50-80 mv more positive than of the nickel-boron, and the Tafel portions of their anodic curves almost coincide.
