    • An iron-containing metal surface, such as a brushed stainless steel, comprises a heat-set layer of a metal phosphate reaction product formed between a surface metal and phosphate precursor wherein the reaction product layer has an average thickness less than 2 micrometers. A metal surface, that resists retention of environmental stains or marks as well as resisting tarnish at elevated temperatures, is formed by forming a reaction product with the metal surface by heat setting a surface liquid layer containing a phosphate precursor such as a phosphate ester-containing solution or phosphoric acid solution, and optionally containing a phospho alumina precursor, onto the metal surface. An article coated in accordance with this invention is similar in appearance to a similar article without such a coating for maintaining original aesthetic properties.
    • 含铁金属表面,例如拉丝不锈钢,包括在表面金属和磷酸盐前体之间形成的金属磷酸盐反应产物的热定形层,其中反应产物层的平均厚度小于2微米。 通过与含有磷酸酯前体的表面液层进行热定型,形成与金属表面反应的反应产物,形成抵抗环境污点或痕迹保留的金属表面,以及耐高温下的抗褪色。 溶液或磷酸溶液,并且任选地含有磷酸铝前体,在金属表面上。 根据本发明涂覆的制品在外观上类似于没有这种用于保持原始美学特性的涂层的类似制品。
