Problems solved by technology

[0005] However, as a marine accessory, although the material can form a protective film on the surface at the initial stage, it has the effect of chemical corrosion resistance, but due to the influence of seawater biological corrosion factors, the performance of chemical corrosion resistance is gradually reduced, and eventually the life of the accessory is shortened. unable to meet demand

Description

technical field [0001] The invention relates to a processing and processing method for marine accessories, more particularly to a marine accessory, a corrosion-resistant treatment method thereof and a corrosion-resistant marine accessory, belonging to the technical field of processing methods for marine accessories. Background technique [0002] With the progress of the overall scientific and technological level, more and more countries have raised the utilization and development of the ocean to the strategic height of national development. In order to develop and utilize marine resources reasonably and effectively, one of the most important aspects is to develop marine accessories with strong corrosion resistance. [0003] Due to the unique nature of seawater, there are many factors that affect the corrosion of marine accessories (such as anchors, steel cables, balance fins, etc.) in seawater environments, including chemical, physical and biological factors. The effects of...
