 Abstract:
The formation of a plasma spray coating is a complex process involving layers of individual splats. These layers of splats not only contribute to the unique coating microstructure, but also produce a distinctive surface. This surface, along with the microstructure, change as the coating layers need to conform to complex substrate geometries. Complex surfaces smaller than the coating footprint were created. The surface topography of plasma sprayed Yttria stabilised zirconia on complex geometries was studied and related to the microstructural properties. A three dimensional profile of the surface was analysed and found the size and frequency of the asperities were related to a directional porosity distribution and mechanical properties.
