Various corrosion characteristics of bright Ni-Cr electroplated steel panels subjected to the CASS test are discussed phenomenally and statistically. The panels exhibited a large degree of variation in the various corrosion characteristics. Changes in the smoothed corrosion characteristics at each thickness of Ni as a function of the CASS test cycle are related to the fact that the barrier effect of the Ni coating increases with increasing Ni thickness. The spatial distribution of the pits followed a Poisson process regardless of the course of the CASS test cycle. The distribution of the Ni thicknesses at the bottom of pores in the Ni coating can follow a logarithmic normal distribution. From these results, it was concluded that the large variation in the corrosion characteristics of bright Ni-Cr electroplating is a natural phenomenon for the pits.
