1.1 本指南描述了结构粘接用铝及其合金的磷酸阳极氧化要求。 1.2 本文包含的程序基于许多机构和组织的商业实践。必要时，可对该方法进行修订或补充，以包括基于经验证性能的方法。 1.3 用于粘合剂鉴定和质量控制测试的金属系统的表面处理应由制造商和用户商定。 1.4 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 具体预防措施见 5.5 . 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 只有通过正确选择和仔细控制所用材料和粘接过程中的步骤，才能可靠地实现金属与金属、金属与复合材料之间的持久粘接。 制备金属基底以获得具有适当特性的表面是一个关键步骤。不适当的表面处理可能会产生表面上可以接受的键，这些键会随着时间的推移迅速降解。本指南介绍了一种如何正确制备铝表面的方法。 4.2 在结构组件中形成可再生、耐用的粘合剂需要在材料选择、待粘合部件表面的制备、部件的装配和粘合过程中步骤的性能方面非常小心。经验表明，当根据本指南制备的粘接铝表面产生相对可再生、耐用的粘接时。

1.1 This guide describes the requirements for phosphoric acid anodizing of aluminum and its alloys for structural adhesive bonding. 1.2 The procedure included herein is based on the commercial practice of numerous agencies and organizations. The method may be revised or supplemented, as necessary, to include methods based on proven performance. 1.3 The surface preparation of metal systems used for qualification and quality-control testing of the adhesive should be agreed upon between the manufacturer and the user. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. A specific precaution is given in 5.5 . 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 Durable adhesive bonds between metal to metal, metal to composites can be obtained reliably only through proper selection and careful control of the materials used and the steps in the bonding process. The preparation of the metallic substrates to obtain surfaces with appropriate characteristics is a critical step. Improper surface preparation can produce seemingly acceptable bonds that can degrade rapidly with time. This guide describes one method on how to properly prepare aluminum surfaces can be obtained. 4.2 The formation of reproducible, durable, adhesive bonds in structural assemblies requires great care in the selection of materials, the preparation of the surfaces of the components to be bonded, the fit of the components, and the performance of the steps in the bonding process. Experience has shown that when adhesively bonded aluminum surfaces which have been prepared in accordance with this guide produce relatively reproducible, durable bonds.
