摘要：

Paint failure on cold-rolled steel sheet occurs by cathodic delamination at the pretreatment/steel interface. Surface contamination, mainly carbon, is primarily responsible. The carbon is not uniformly distributed, and its presence in localized areas interferes with the formation of zinc phosphate during pretreatment. The carbon in amorphous elemental form probably originates during annealing from the breakdown of residual rolling oils left on the surface prior to annealing and from the thermal dissociation of carbon monoxide.
