High speed wear testing of an abradable coating
This paper is the output of research council (EP/H023895/1 - £100k) and industry sponsored research into aero-engine abradable linings (used on the insides of compressor and turbine casings). It is the first time that adhesion of material to the blade has been imaged during the rub process. Crucially, this shows wear and adhesion occur simultaneously – events previously thought independent. For the sponsor, Rolls-Royce, performance of abradable materials is critical to engine efficiency, as adhered material can break away and cause combustor blockages (contact: Surface Engineer). It led to further Rolls-Royce funded work (£75k) and a co-sponsored PhD studentship (£33k).
