Arc Sprayed Steel: Microstructure in Severe Substrate Features

Abstract:

The effect of severe substrate topography on the microstructure of thermally sprayed coatings has been relatively neglected, but is critical in controlling the performance of thick electric arc sprayed steel shells for rapid tooling applications. This paper shows how the spray angle and the atomizing gas pressure control the distribution of porosity and oxide in steel sprayed in and around cylindrical holes of different diameter and depth. Droplet splashing and the secondary deposition of spl...
