酸洗对锆合金管材超声检测结果的影响分析

Effect of Pickling on Ultrasonic Test of Zirconium Alloy Tubes

分析了锆合金管材表面缺陷在酸洗前后的去除情况,研究了酸洗对超声检测效果的影响。分析表明,适当的酸洗工艺可以消除锆合金管材表面的微小缺陷,改善管材的表面质量;但酸洗不能彻底消除管材中的裂纹状缺陷,反而会影响缺陷对超声波的反射效果,甚至会使超声检测出现漏检。

This paper analyzes the removal of surface defects of zirconium alloy tube before and after pickling, and studies the effect of pickling on ultrasonic detection. Analytical studies have shown that proper pickling processes can eliminate the small defects in the surface of zirconium alloy tube and improve the surface quality of the tube. But pickling cannot completely eliminate the crack defects in the tubes, and it may affect the ultrasonic reflection by defects, and even cause defects undetected.
