Abstract:

In this paper we present a unique nondestructive inspection NDI system for inspection of AlSiC metal matrix composite MMC inserts in cast aluminum tank track shoes TTS. The system is based on two different nondestructive inspection methods, ultrasonics UT and eddy current EC, which are capable of detecting and identifying defects in MMC, such as porosity, debonding, and cracking. This paper also discusses results obtained during inspections of AlSiC MMC samples with different levels of porosity, and debonds using UT and EC inspection. The prototype version of the system is designed to perform an acceptance inspection after TTS manufacturing and before deployment. Other potential applications of this system are in the evaluation of complex MMC parts in the automotive industry.
