某炮弹底塞表面防护工艺霉菌试验研究

目的研究某炮弹底塞最佳表面防护工艺。方法采用霉菌试验方法,对2种底塞材料多种表面处理与防护工艺样品的防霉性和防腐蚀性能进行试验和优选。结果分析了防霉性和防腐蚀性能优劣的原因,评定出了最优的材料和表面处理与防护工艺组合,提出了炮弹长贮防霉和防腐蚀的建议和措施。结论底塞最佳的材料和表面处理与防护工艺组合为30Cr Mn Si A+镀锌/镀锌镍合金+涂7258号航空润滑油脂。

Mold Test of Surface Protection Technology for Base Plug of a Type of Bullet

Objective To study the optimal surface protection technology for Base Plug of a type of bullet. Methods Mold test method was used to test the anti-mold property and corrosion resistance of specimens of two kinds of base plug materials processed by different protection technologies. Results The causes for the different corrosion resistance and anti-mold performance was analyzed, the optimal combination of material and surface protection technology was selected, and some suggestions and measures for long storage and corrosion proof of bullets were put forward. Conclusion The optimal material and surface protection technology for base plug of bullet was 30CrMnSiA + galvanizing/zinc-nickel alloy coating + coating with 7258 aviation grease.
