前言
国际标准化组织 (国际标准化组织) 是国家标准机构的全球联盟 (ISO成员机构). 国际标准的制定通常通过ISO技术委员会进行. 对已成立技术委员会的主题感兴趣的每个成员机构都有权在委员会中派代表参加. 与标准化组织联络的政府和非政府国际组织也参与了这项工作. ISO 与国际电工委员会密切合作 (国际电工委员会) 关于电气标准化的所有问题.

用于制定本文件的程序以及用于进一步维护的程序在第 1 部分中进行了描述。 1 ISO/IEC 指令的. 尤其, 应注意不同类型ISO文件所需的不同批准标准. 本文件根据部分编辑规则起草 2 ISO/IEC 指令的 (请参阅 iso.org/directives).

介绍
Phosphate conversion coatings are applied to ferrous metals, 铝, zinc and their alloys (including galvanized and zinc-alloyed steel, cadmium and their alloys) as end faces or as interlayers for other coatings. They are designed to

— Imparts corrosion resistance,

– Improves adhesion to paints and other organic finishes,

– promote cold forming operation, such as drawing, tubing, and extrusion, 还有

– Modification of surface friction properties to facilitate sliding.

Phosphate conversion coating is produced by solution treatment, its main composition is proper orthophosphoric acid dihydrogen salt. These coatings are mainly applied to ferrous materials and zinc, and the coating quality and apparent density per unit area vary depending on

– component of building materials and surface condition,

– prior to mechanical and chemical processing of parts, 还有

– phosphating treatment conditions.

More or less all phosphate conversion coating is porous, but can be by subsequent sealant for which the material sealing process.
