Neutron diffraction residual strain measurements of nanostructured WC-Co coatings. [Dataset]

Abstract

Thermally sprayed WC-12%wt.Co coatings are used in aerospace, energy and marine applications to combat wear. The failure of these coatings is dictated by residual stress which can lead to catastrophic delamination of coatings. Previous studies have indicated that conventional measurement techniques such as X-rays and synchrotrons do not provide the required penetration depth for through thickness residual stress evaluation. The stress profile of these coatings can be altered by the use of recent advancements which utilise nanostructured coating materials is suspension spraying. The aim of this 2-days beamtime proposal is to investigate the residual stress profile (through thickness) in these nanostructured (200-500 nm crystal size) WC-12%Co coatings with a view to model stress build-up using neutron scattering facility (SALSA) using the vertical scan mode.
