| 摘 要： | 采用声发射(AE)技术实现动态监测4043铝合金/氧化铝涂层系统的拉伸实验过程。通过SDAEA信号分析系统对拉伸过程中AE信号幅度、能量、振铃计数、撞击速率以及波形和其傅里叶变换(FFT)进行了分析。揭示出4043铝合金/氧化铝涂层系统拉伸过程中涂层裂纹萌生和扩展过程,并且通过分析AE信号随时间的变化规律得出涂层材料的面内拉伸强度和涂层结合强度。

| Abstract: | Acoustic emission(AE)technology was used during tensile tests to detect in real time the tensile behavior and damage evolution of the Al2O3/4043Al-Alloy system.The SDAEA signal analysis system was applied to analyze the amplitude,energy,ringing-counts,impacting speed rate,waveforms and FFT of AE data.The emergence and evolution of microcracks with Al2O3 coating was recognized during tensile process,the in-plane tensile strength and the cohesive strength of Al2O3 coating were also introduced by analyzing the... |
