Abstract

PURPOSE: To obtain a steel plate of excellent corrosion resistance, superior secondary adhesiveness of paint films and superior stripping resistance of the paint films coated on paint surfaces by plating Ni-Zn alloy on the surface of a steel plate then forming a chromate film on the plated surface.
CONSTITUTION: A steel plate as an exterior panel material for automobiles is first plated with an Ni-Zn alloy of 9W20% content of Ni. This Ni-Zn plated steel plate is immersed in an aq. soln. contg. CrO3, H2SO4, whereby a chromate film of ≤1W5mg/m2 Cr pickup is formed. If paint is coated on this, the paint film is difficult to strip off from the steel plate, and the external panel material of superior corrosion resistance for automobiles is obtained.
