腐蚀破坏是结构材料最重要的破坏形式之一,它是机械设计中不可忽视的重要因素。因此,设计人员不仅要考虑设备构件的功能作用,还必须考虑腐蚀环境中的防护措施,以减轻或防止腐蚀所造成的危害。防腐设计是针对现代机械工程腐蚀这一重大现实问题而迅速发展起来的一门新技术。所谓防腐设计,就是在设计阶段应用材料腐蚀和保护的基本理论,为预防机械设备腐蚀破坏和损失而考虑的设计。它主要包括五方面的内容.一、材料的选定现在可作为机械设备的材料很多,除了各种金属 Corrosion damage is one of the most important forms of damage to structural materials, which is an important factor that can not be ignored in mechanical design. Therefore, the designer must not only consider the functional role of equipment components, but also must consider the protective measures in the corrosive environment to reduce or prevent the harm caused by the corrosion. Anticorrosive design is a new technology that is rapidly developed in response to the major realities of corrosion in modern mechanical engineering. The so-called anti-corrosion design, that is, in the design phase of the application of material corrosion and protection of the basic theory, to prevent corrosion damage and loss of machinery and equipment to consider the design. It mainly includes five aspects. First, the choice of materials can now be used as a lot of mechanical equipment materials, in addition to a variety of metals
