| Abstract: |
| The work aims to improve anti-corrosion properties of vehicle equipment in tropical island-reef atmospheric environment, so as to provide evidence of anti-corrosion design and modification for long-term stable service of vehicle equipment in tropical island-reef atmospheric environment. Under analysis on island-reef environment characteristics and research and summary on corrosion rule of vehicle equipment, corresponding corrosion protection design and countermeasures were formulated and then applied to the vehicle equipment for verification. According to corrosion characteristics, vehicle equipment corrosion was classified into four types, including structure corrosion, electrical product corrosion, material corrosion and coating corrosion. Structure corrosion was the major corrosion behavior. The main kinds of corrosion types of structure corrosion were crevice corrosion, galvanic corrosion, corrosion caused by structural edge and water-logging structure, etc. In terms of corrosion environment, the vehicle equipment was divided into four areas , which consisted of fully exposed structure outside the cabin, bottom of chassis, area inside engine cabin and area in cabin. The corresponding corrosion protection design and countermeasures were adopted to the vehicle equipment, including corrosion protection design of classical structure and electric product, optimal selection of materials and coatings, measures of maintenance, corrosion monitoring technique, which achieved good results in practical applications. According to different types of corrosion, corresponding corrosion protection designs and countermeasures, such as structure and electric anti-corrosion design, reasonable selection of material and coating, anti-corrosion method of repair and maintenance, strict environmental testing, and corrosion monitoring, can be adopted to help vehicle equipment maintain long-term and good environmental adaptability in tropical island-reef environment. |
