Suspension and solution precursor (SSP) spraying is an emerging thermal spraying technology which utilises liquid feedstock containing sub-micrometre and nanoparticles. Alumina (Al2O3) is a widely used engineering ceramic and it has excellent dielectric and tribology properties. It has already been demonstrated that suspension sprayed alumina provides two orders of magnitude wear protection compared to traditional high velocity oxy-fuel (HVOF) or atmospheric plasma sprayed coatings. In this proposal, through thickness neutron diffraction (at ENGIN-X) residual strain measurement is proposed using the vertical scan mode. This is the first study on residual strain measurement using neutron diffraction of a suspension sprayed coating. Two coatings sprayed at 72 kW and 101 kW flame energy will be provided by the investigators and their high temperature behaviour will be investigated.
