爆炸复合接头防锈铝/防锈铝层界面结合品质的超声检测

摘要

Metallographic test,shear test and penetrate testing are processed in the Antirust aluminum/rust layer of explosive composite joint interface which has obvious interface echo.And we compare the data,and get in the ultrasonic testing antirust aluminum/rust layer interface between interface echoes,there is melting block anti-rust aluminum/antirust aluminum melt layer interface between them and its size is greater than 0.2 mm.We do the penetrate examination of the antirust aluminum interface,and there is linear and dot in the melting area.We use ultrasound tests to evaluate aluminum steel composite joint interface bonding quality,which can judge the interface microstructure and shearing,and determine the optimal process quickly without any damage.%对爆炸复合接头防锈铝/防锈铝层界面有明显界面回波的区域进行了金相试验、剪切试验和渗透检测,并对数据进行了分析比较,得到在超声检测防锈铝/防锈铝层界面之间出现界面回波,防锈铝/防锈铝层界面之间有尺寸大于0.2 mm的熔化块.对防锈铝界面进行渗透检测,熔化块区域出现线性和点状显示.采用超声检测法评估铝钢复合接头界面结合品质,可以无损快速判断界面金相和剪切情况,判定最优工艺.
