On ceramic frit side the bonding was poor with a 19% cohesive failure before APPT treatment, see Fig. 11. The treatment with both APPT with just air improved the bonding to a fully cohesive failure, which is the best result that can be measured. A fully cohesive failure was also seen with APPT with deionized water as precursor.
