Acoustic Emission of Lead Components Simulating Feasibility of the Corrosion and Oxidation of Plutonium Materials

Acoustic emission testing is a non-destructive testing method to detect the internal defects of materials by using the acoustic properties of the materials and their defects. Acoustic emission detection has been a hot spot in nondestructive testing, and acoustic emission nondestructive testing has the characteristics of reflection, refraction and waveform conversion at the interface. Through the analys of simulation results,ultrasonic pulse reflection method is feasible to detect corrosion defect and oxidation layer density change of lead components.By studying the similarity of lead and plutonium’s acoustic characteristics, it is supported theoretical platform of radioactive plutonium components.The test used by lead material instead of plutonium material components was conducted by ultrasonic inspection. Software simulated lead oxide corrosion.
