摘要 采用电化学工作站,扫描电镜(SEM),透射电镜(TEM)等方法,研究了Al-5Ti-1B与Al-5Ti-0.2C晶粒细化剂对预涂感光版(PS)用1050铝板基的微观组织及腐蚀性能的影响。结果表明:采用Al-5Ti-1B细化剂的铸轧板中存在粗大的铁、硅第二相,PS版铝板基中存在聚集第二相和位错缠结,电解腐蚀时,出现局部腐蚀严重,腐蚀孔洞分布不均匀等现象;添加Al-5Ti-0.2C晶粒细化剂的铸轧板中,铁硅相相对细小,分布也更加均匀,无聚集现象,PS版铝板基中第二相细小弥散,分布均匀,电解腐蚀时,腐蚀速率快,腐蚀均匀,电解腐蚀性能得以改善。

Abstract:By using electrochemical workstations, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and other means,the effects of two kinds of grain refiners, Al-5Ti-1B and Al-5Ti-0.2C, on microstructures and properties of 1050 aluminum presensitized plate were investigated. The results show that there are numerous coarse second-phase particles containing Fe and Si in the cast-rolling board added Al-5Ti-1B. There are second phase particles and tangled dislocations in presensitized plate, which result in strong local corrosion and ununiformity of corrosion holes. However, in the cast-rolling board added Al-5Ti-0.2C,the second-phase particles containing Fe and Si, are relatively smaller and more uniform, without aggregation. The second-phase particles in presensitized plate are in small dispersion and uniform distribution, which lead to the acceleration of electrochemical corrosion and more uniform corrosion. For the plate added Al-5Ti-0.2C, the properties of electrolytic corrosion were improved.
