Hi victor,
can you be more specific?
Do you use APS? I have some experience with APS sprayed YSZ coatings and we solved this problem too. You can try change primary and secondary gas flows, spraying distance, arc current and feeding rate as well. So many parameters how to fix your top coat porosity. You can ask me thru my personal e-mail.
