Madan, M and Sujata, M and Raghavendra, K and Gore, P and Bhaumik, SK (2011) Failure analysis of IC engine valve. Project Report. National Aerospace Laboratories, Bangalore, India.Full text not available from this repository.
Analysis of the fractured sample showed that the cracks in the valve were generated due to hydrogen embrittlement (HE). The valve steel picked up hydrogen during chrome plating and/or chemical etching process. The high hardness of the valve in the groove region made it more susceptible for HE cracking. The valve provided for comparative study also showed presence of a crack in the induction hardened zone and adjacent to the groove. A detailed analysis of the failure is presented in this report and a few recommendations suggested.
