Hammad Nazir: In-situ corrosion health monitoring and prediction in military vehicles

Researcher: Hammad Nazir

SDRC has formed strong partnerships with Defence Science & Technology Laboratory (DSTL) Ministry of Defence and The Tank Museum in structural integrity research.  Hammad Nazir is conducting PhD research into this area and started his work early this year. Hammad has a Master degree in Electrical Engineering with Distinction and worked at ABB Group – Automation and Power Technologies Sweden. The proposed research will focus on the structural corrosion of military vehicles and provide insights that will be useful for museums and historians hoping to preserve such vehicles for the future.

The Tank Museum at Bovington is one of the world’s largest museums which has over 300 historic military vehicles. These vehicles are subject to structural deterioration through corrosion, corrosion fatigue, stress corrosion cracking and mechanical failures. The Tank Museum at Bovington match funded (£25K + £3600) a PhD research programme in “Sustainable Methodology of Conserving Historic Vehicles.” This project provided an understanding of military vehicle preservation from a predominantly technical viewpoint with aspects of project management and ethics of museum artefacts.

The findings have also attracted international industrial players in corrosion, structural deterioration and materials’ characterisation, who have been involved through in-kind support such as NASA Materials Testing and Corrosion Control Branch (joint research publication), BAE Systems, Technology Design Limited, PANalytical Ltd, Analatom, PMI Analytical, Carl-Zeiss Cambridge and West-Dean Chichester (in kind £21K in total) in experimental resources.

The current research in “In-situ corrosion health monitoring and prediction in military vehicles” is match funded (£22.5K, Dr. Zulfiqar Khan PI)  by Defence Science and Testing Laboratories (DSTL), Ministry of Defence.

 

Objectives of research:

The current research is investigating failure mechanisms through corrosion in military vehicles. Corrosion bench-testing simulation will be designed to conduct structural deterioration tests both in non-corrosive and aggressive-corrosive environments. These tests will be complimented through state-of-the-art carrion in-house simulation techniques in varying temperatures and humidity ratios. In-situ novel techniques will be developed for sensing     corrosion residues at micro and sub-micron levels. Finite element and classical mathematical modelling techniques will be developed for life prediction.

Methodology:

Corrosion simulations will be designed to perform tests within non-corrosive and aggressive environments through a Temperature-Humidity test chamber. Mathematical modelling will be developed to predict corrosion propagation. In-situ novel corrosion sensing methodology for monitoring corrosion residues at micro and sub-micro levels will be designed & developed through novel micro-sensing techniques.  A generalised mathematical model and GUI will be developed for corrosion assessment.
