涡流C扫描在钛合金SPF/DB结构检测中的实验研究

为了探索SPF/DB结构检测中有效的检测方法,应用涡流C扫描对钛合金SPF/DB结构进行了检测实验,将涡流C扫描结果和SPF/DB结构检测中常用的超声C扫描结果进行了对比分析。结果表明,涡流C扫描能够检测出SPF/DB结构的界面宏观缺欠以及一定尺度以上的界面微观缺欠,在SPF/DB结构检测中是可行的。有必要对该检测方法的有效性和检测结果的可靠性进行深入研究。

Investigation of Eddy Current C-Scan in Testing of Titanium Alloy SPF/DB Structure

Eddy current C-scan testing experiment is carried out to investigate the effective testing method in testing of SPF/DB structures. Compared with the results of ultrasonic C-scan, the results of eddy current C-scan are analyzed. It is shown that eddy current C-scan can inspect the imperfections like macroscopic interface imperfection and microcosmic interface imperfection with a certain scale. Eddy current C-scan is a feasible testing method for SPF/DB structures. It is necessary that availability and reliability of eddy current C-scan for SPF/DB structures are studied more deeply.
