Title:
後処理被膜が形成された亜鉛系めっき鋼板及びその後処理方法
Document Type and Number:
Japanese Patent JP6684910
Kind Code:
B2
Abstract:
The present invention relates to a zinc-based plated steel sheet having a post-treated coating filmed thereon comprising: a steel sheet; a zinc plated layer formed on the steel sheet; and a post-treated coating formed on the plated layer, wherein the atomic ratio (O/M) of oxygen (O) to metals (M) contained in the post-treated coating is greater than 2 and less than 20, and a method for post-treating a zinc-based plated steel sheet. According to this, the zinc-based plated steel sheet having the post-treated coating formed thereon has the effects excellent in lubricity, weldability, adhesiveness, film-removing property and paintability. As the method of post-treating a zinc-based plated steel sheet of the present invention employs a simple coating method irrespective of the kind of plating layer, the process is simple and economical and the process operation cost is low.
