摘要
将金相复膜技术运用在水电站弧形闸门裂纹缺陷诊断中,详细探讨了金相分析流程及常规金相技术与金相复膜技术的区别与联系,解析有机玻璃+氯仿组合的复膜材料及丙酮+醋酸纤维纸的优缺点及具体工程运用技巧,确定了闸门支铰复膜时间、复膜次数及化学浸蚀时间。
Metallographic Replica technology is applied to the crack defect diagnosis of radial gate of hydropower station.The metallographic analysis process and the difference and relation between conventional metallographic technology and metallographic Replica technology are discussed in detail.The advantages and disadvantages of laminating materials of Plexiglass+Chloroform and Acetone+Acetate fiber paper and the specific engineering application skills are analyzed.The replicating time,replicating times and chemical etching time of gate hinge are determined.
