Plasma transferred arc cladding of Ni-Cr-B-Si coating on copper substrate

Materials Letters: X, 2022
Aiming to improve the surface properties of copper, a Ni-Cr-B-Si coating was fabricated by plasma transferred arc (PTA) cladding. The coating formed a good metallurgical bonding with the copper substrate, and the dilution rate was about 15.9%.
