基于海洋环境的紧固件腐蚀防护要求及技术措施

Corrosion Protection Requirements and Technical Measures of Fasteners Based on the Marine Environment

紧固件是实现机械连接大量采用的一种最常见方式,是机械工业中的关键基础零部件。紧固件在各种环境中的腐蚀一直是设计者面临的问题。解决紧固件腐蚀的方法很多,表面处理是其中的重要方法之一。简要分析了紧固件腐蚀防护的基本措施和思路,着重从表面处理技术和结构防腐出发,讨论了紧固件表面涂层在不同工况下的使用要求,提出了表面处理方法和防腐结构设计。

The fastener which is extensively used in mechanical connection as one of the most common methods,is the infrastructure component in the machinery industry. However,the corrosion of fasteners in a variety of environments has always been a big problem that designers have to face. There are many methods of solving fastener corrosion, among which the surface treatment is one of the important methods. The basic corrosion protection measures and ideas for fastener were briefly analyzed. Focused on the surface treatment technology and structural anti-corrosive, the requirements of surface coatings in different operation conditions were discussed. In addition, surface treatment methods and corrosion structural design for fasteners were proposed.
