BCW Manufacturing Group would like to congratulate DR J.C Avelar-Batista Wilson – Treatments Technical Manager within BCW Treatments on her recent publication with publisher Elsevier and in partnership with the School of Chemical and Process Engineering, University of Leeds.
The publication titled “Sample preparation of anodised aluminium oxide coatings for scanning electron microscopy” was developed alongside Jonathan Long and Dr Antonia Borissova (Leeds School of Chemistry) and Dr Andrew Wilson. The authors would like to thank the Regional Growth Fund (RGF) for financial support received from Project/Programme Reference No 01.09.07.01/2584C. They are also greatly indebted to Mr Stuart Mickelthwaite of Leeds Electron Microscopy and Spectroscopy for his much-valued assistance with SEM and to Buehler for their expertise and assistance with metallographic preparation.
Here is the abstract of the publication:

Characterisation of anodic aluminium oxide coatings and measurement of their thickness using microscopic techniques is valuable for analysing the effectiveness of the prior anodising process. Three different methods for preparing samples to view the coating cross-section (mechanical fracturing, cryogenic fracturing and metallography) were trialled and assessed for speed of implementation, simplicity and achievable measurement accuracy.
Cryogenic fracturing was found to be destructive to samples. Mechanical fracturing yielded relatively
accurate coating thickness measurements and coating structural information. Metallography provided the most accurate coating thickness measurement at the expense of coating structural information.
