The Adjustment of the Turn-to-Turn Contact Resistance of REBCO Tape by Stripe Shape Stainless-Steel Coating

In this paper, the stripe shape stainless-steel coating on the commercial REBCO tape was attempted to adjust the turn-to-turn contact resistance. The original plan is to use a stripe SS coating to create the space between the two REBCO tapes and maintain the path on the SS coating part, which can significantly increase the contact resistance by decreasing the contact area. In real conditions, the SS coating did not reach its goal but created alternative pathways of SS-SS contact and Cu-Cu contact, which can also partially adjust the contact resistance. It is believed that the contact resistance can be controlled in a larger range by changing the coating materials.
