In a joint development project, TACR GmbH1 and H.C. Starck GmbH2 took an approach to adjust the properties of an agglomerated and sintered YSZ powder to a process setup optimized for a HOSP type powder. Within the OEM approved process parameters, which could be changed within narrow limits only, the particle size distribution of the agglomerated and sintered powder was adjusted to meet process parameters and spray setup. Key parameters for the comparison of coating properties and spray behavior were coating porosity and deposition efficiency (DE).
