热喷涂.锌 铝及其合金.第1部分:防腐蚀系统的设计考虑和质量要求

[中文适用范围]： 本文件规定了通过使用锌、铝或其合金的热喷涂金属涂层来保护钢铁表面免受腐蚀的要求。 在本文件中，规定了腐蚀防护系统的规划和要保护的部件的结构设计的要求，其中热喷涂旨在作为金属腐蚀防护沉积的过程。 定义了一些与现场相关的基本术语，并提供了锌、铝材料在不同环境条件下的腐蚀行为说明。 规定了涂层的特性，例如涂层厚度、最小粘合强度和表面外观，并确定了锌、铝或其合金热喷涂防腐蚀涂层的测试程序。 本文件适用于在 -50 °C 至 +200 °C 的温度范围内涂敷热喷涂锌和铝防腐蚀保护涂层，并考虑到所使用的任何密封剂的使用条件。 铝的耐热保护涂层涵盖了其他防腐蚀工艺，例如热浸镀锌（电镀涂层）、渗锌、电镀或有机涂层/油漆的选择和沉积，不属于本文件的范围。 ISO 2063-2 规定了热喷涂涂层的制造要求。 [外文原描述]： This document specifies requirements for the protection of iron and steel surfaces against corrosion by applying thermal-sprayed metallic coatings of zinc, aluminium or their alloys. In this document, requirements for the planning of the corrosion protection system and for the constructive design of the component to be protected are specified, where thermal spraying is intended to be the process for the deposition of the metallic corrosion protection. Some field-related basic terms are defined and instructions for corrosion behaviour of the zinc and aluminium materials under different environment conditions are provided. Characteristic properties of the coating, e.g. coating thickness, minimum adhesive strength and surface appearance, are specified and test procedures for thermal-sprayed corrosion protection coatings of zinc, aluminium or their alloys are determined. This document is valid for applying thermal-sprayed zinc and aluminium protection coatings against corrosion in the temperature range between −50 °C to +200 °C, taking into consideration the service conditions of any sealants used. Heat-resistant protective coatings of aluminium are covered by ISO 17834 and are not in the scope of this document. Other corrosion protection processes, e.g. hot-dip galvanizing (galvanic coating), sherardizing, electroplating or selection and deposition of organic coatings/paints are not in the scope of this document. Requirements for the manufacturing of thermal-sprayed coatings are specified in ISO 2063-2.
