黄铜药筒表面防锈ATA自组装膜实验研究

Study on Rust Prevention of the Self-assembled Monolayers of ATA on Brass Case

黄铜药筒长期储存过程中表面易发生锈蚀,严重影响了弹药的正常使用。ATA具有很强的螫和性,是一种有效的环境友好型金属缓蚀剂,在黄铜药筒表面包覆ATA自组装膜对缓解药筒锈蚀具有一定的可行性。笔者通过试验在黄铜药筒表面包覆ATA自组装膜,采用EDS能谱分析,电位-时间曲线对对药筒表面覆膜情况进行了分析,通过失重实验初步研究了表面覆膜黄铜药筒在酸性环境下的抗腐蚀性能。结果表明:本方法可以在黄铜药筒表面包覆ATA自组装膜,且在酸性环境下覆膜药筒有较好的防锈缓蚀性能。

Brass case long-term storage process surface prone to coeeosion, which seriously affects the normal use of ammunition. ATA has strong chelating sex, is a kind of effected environmental friendly metal corrosion inhibitor, in brass case surface coated ATA self-assembly menbrane to ease the case corrosion has certain feasibility. This article through the experiment in the brass case surface coated ATA self assembly membrane, adopted EDS energy spectrum analysis, potential-time ease curve of coated surface was analyzed and studied by weightlessness experimental preliminary case coated brass surface in acidic environment of corrosion resistance. The test results show that the method can coat ATA self-assembly menbrane in brass ease and the coated brass case has excellent rust preventive property in acidic envi ronment.
