根据雷达天线骨架所处的腐蚀环境，设计了相应的防腐配套方案以及表面处理、电弧喷锌和喷底、面漆等涂装工艺技术参数。认为雷达在使用过程中处于C5甚至C5-M的严重腐蚀大气环境的概率较高，应以环氧或聚氨酯漆为电弧喷锌层的封闭涂层(膜厚25~30 mm，不计入规定的膜厚)，并适当增加锌层上中层漆和面漆的膜厚，并推广应用抛丸除锈法和无气喷涂法以提高涂装质量，延长雷达的使用寿命。
A scheme for corrosion protection of radar antenna framework was designed based on the corrosion environment where it is usually located. The technological parameters for surface pretreatment, zinc arc spraying, as well as primer and topcoat spraying were presented. Considering the high probability of radar in highly corrosive atmosphere environment of C5 even C5M during application, it is suggested that the arc sprayed zinc coating should be sealed with epoxy or polyurethane paint (thickness 25-30 mm, not included in the stipulated thickness) and the thicknesses of midcoat and topcoat on zinc coating should be appropriately increased. Shot blast rust removal and airless spray should be popularized to improve the coating quality and prolong the service life of radar.
