As part of his studies into 4-D micro tomography of pit to crack transition, PhD student Muntasir Hashim has been able to develop a method whereby pits are made using different electrochemical methods. And, in doing so, produced stunning images.
By using electrochemical methods, Muntasir was able to create 3-D profiles of corrosion pits from the inside of metal, generated using X-ray computer tomography.
The resulting images show pits of different diameter sizes, with the best results being obtained using a micro-capillary cell, which was developed to integrate a manipulator and ultra-zoom camera to easily create localised corrosion in desired locations on any flat specimen.
The images provide excellent insight into the patterns of corrosion, and as images, have an element of their own artistic merit.
Muntasir presented the images as part of his presentation titled ‘Influence of Pit Morphology on Crack Propagation’ at the 2017 NSIRC Annual Conference.
He received his BEng in Aerospace Engineering degree from Brunel University London in 2014 and did several work placements at Nikon Metrology, where continued working there after graduation, developing an interest in X-ray Computed Tomography studies. In 2015, he joined NSIRC PhD programme, with the University of Manchester and sponsored by Lloyds Register Foundation.
