What does Safety, Reliability & Durability mean to you?

innovation, PG research, Publishing

You must have heard about the recent tragic accident at Alton Towers. Unfortunately it involved one of the most popular rides, the Smiler. Accidents are bound to happen due to various reasons e.g. human error or faults in mechanical, electrical, electronics or control systems/components. Some of the accidents are catastrophic and involves the loss of human lives that includes today’s (Saturday August 22, 2015) vintage plane crash at the air show at Shoreham.

Among several reasons, corrosion is one of the major phenomena which plays an important role in structural deterioration and compromising reliability and durability of components, systems within petrochemical & process industries, automotive, locomotive and aircrafts.

Special attention to corrosion in terms of design, detection and prediction of failures is needed especially where human lives are involved. Here are some of the images from major international and home theme parks where there are visible signs of structural deterioration. Although corrosion initiation, its propagation and affects on structural deterioration may not be physically and visually very prominent, it needs full attention to avoid accidents. IMG_4234 IMG_4235 IMG_4386 IMG_4387 IMG_4388

A significant portfolio of research & development in corrosion has been developed at BU, which responds to structural integrity issues. Earlier work [15-17] in corrosion fatigue has led to a successful research portfolio in corrosion at BU [1-17]. We have developed a meso-mechanics based approach incorporating fracture mechanics and electrochemical processes to predict corrosion through a novel holistic modelling tool.

A PhD degree research in sustainable methodology of conserving historic military vehicles subject to structural deterioration due to corrosion [13, 14] has been successfully completed. This research was conducted in collaboration with The Tank Museum at Bovington. Controlled environment within the newly designed VCC (Vehicles Conservation Centre) is informed by the outcomes of this research. In addition NASA [13] has also been collaborating in corrosion research at BU along with BAE Systems and Analatom Inc. Discussions with Analatom are currently in progress for further collaboration in corrosion sensors technology.

A second project in corrosion monitoring techniques in collaboration with Defence Science & Technology Laboratory Ministry of Defence, through a match funded PhD is currently in progress [1-5]. Recent publications [2-4] from this research have made to the Taylor & Francis top 20 most read articles list. This is an evidence of novel contributions to corrosion and corrosion modelling techniques.

A third project in collaboration with Defence Science & Technology Laboratory Ministry of Defence through BU match funded PhD programme has been awarded to look into wireless corrosion monitoring techniques.

In addition nano coatings (in collaboration with Schaeffler, a major industrial partner) have been developed at BU incorporating corrosion issues to solve current corrosion problems within industrial applications.

A collaborative research project with National University of Science & Technology & Future Energy Source Ltd (the overall portfolio includes 2 x fully funded PhDs, 2 x match funded PhDs and 1 x Post Doctoral Research Assistant, PDRA) is currently underway to investigate corrosion issues within thermal storage applied in renewable technologies.

We have state of the art corrosion bench testing (environmental simulation) and modelling tools. We have micro LPRs (Linear Polarisation Resistors) & MEMS (Micro Electrical Mechanical Systems) based live corrosion monitoring stations for large stationary and moving vehicles.
