Stainless steel tapes are dip coated with a tape withdrawal speed of ~16 mm/s, dried at ~300 °C for 10-20 seconds, followed by a calcination process at 600 °C.  This system consists of a pay-off and a take-up spool with a driving mechanism, a vertical two zone furnace, and a dip tank. The sol-gel solution to powder loading ratio was fixed at a composition that contained enough sol-gel solution to bind the powder to produce thick and adherent coating.
