Abstract

While there has been a consensus that using Mg vapor improves the poor adhesion of MgB₂, it is also known that working with this is hazardous due to its flammable nature. Here, electrophoretic deposition (EPD) is used to fabricate MgB₂ coatings on Cu sheets. Instead of annealing with excess Mg or in the presence of Mg vapor, the as-prepared coatings are subjected to uniaxial pressing to force the coatings to adhere. Results show that the additional heat treatment step produced impurities due to substrate oxidation and alloying, whilst no significant difference in T_c is found for both coatings compared to the bulk T_c value of 39K. Surface images show no cracks which are the primary cause of coating delamination.
