Abstract:
This research is aimed to examine through Non-Destructive Testing (NDT) the material behavior under in-use conditions of an internal combustion engine (ICM) camshaft. The material composition is identified by X-ray fluorescence spectrometry (XRF) approximated to a low carbon 1025 semi mild steel through ASTM E1085 2016, ASTM E3-2017 and ASTM E-407. For wear identification, several tests that can be applied to a camshaft were performed among which we can mention: visual inspection (VT) through UNE-EN 13018, Infrared Thermographic (IRT) with the specifications of ISO 18434-1, Penetrating Dyes (PT) according to ASTM E 165-02, Ultrasound (UT) based ASTM A388-19, the analysis is performed on the surface of the cams and support journals of the camshaft. To determine the reliability of the results, an analysis of the tests described in the same area is performed, the method of greater scope is ultrasound for having greater inspection coverage; the design was validated by CAE Computer Aided Engineering software in which simulations and finite element mechanical analysis were performed to determine the safety of the system.
