高耐蚀性彩色钢材的制造方法
摘要：
本发明通过在被氮化处理的钢材表面进行氧化热处理而形成彩色氧化膜层，由此提供耐蚀性强且表面色彩多样而美观的高耐蚀性彩色钢材的制造方法。所述方法包括下述步骤：(a)对钢材进行氮化处理；以及(b)对经过上述(a)步骤处理的钢材实施研磨、抛光、磨光等表面加工，然后在100℃～700℃的氧化性气氛中进行30秒～100小时的氧化热处理，由此在钢材的表面上形成彩色氧化膜层。
摘要（英）：

The present invention provides a method for producing a highly corrosion-resistant colored article made of steel, which are highly corrosion-resistant and has a variety of vivid surface colors, by subjecting the surface of a nitrided steel article to oxidizing heat treatment to form a colored oxide film layer. The method for producing a highly corrosion-resistant colored article made of steel includes the steps of (a) subjecting an article made of steel to nitriding and (b) subjecting the steel article thus treated in step (a) to surface processing such as abrasion, buffing, polishing or the like, and then to oxidizing heat treatment in an oxidizing atmosphere at 100 to 700 DEG C. for 30 seconds to 100 hours, to form a colored oxide film layer on the surface of the steel article.
