Abstract
Electrically insulating AlO—SiOthin coatings have been deposited on long-length 316 stainless steel (SS) tape using a reel-to-reel continuous sol-gel dip coating process for co-winding insulation into YBCO pancake coils, a high temperature superconductor magnet technology. Coatings with a thickness of ˜2 μm are achieved after just one dip with a tape withdrawal speed of ˜16 mm/s (1 m/min) and a calcination at 700° C. The coatings were measured to have a room-temperature breakdown voltage of about 100 V, corresponding to a dc dielectric strength of about 50 MV/m. Consequently, this process has low cost and high throughput and produces a thin electrical insulation with excellent thermal, dielectric, and mechanical properties. A new technique has been developed in the coating process to mitigate coating buildup near the edges of the tape.
