Passivation of copper films with magnesium doping using recoil ion implantation

A perspective on conducting oxide buffers for Cu-based YBCO-coated conductors

“…In metallurgical applications, Cu oxidation resistance has been enhanced by several approaches, including alloying or implanting elements such as Mg, Cr and Al that are known to be oxygen getters [17][18][19][20][21][22]. Among these, the Mg-Cu and Al-Cu systems are perhaps the most attractive as compared to the Cu-Cr system, due to the limited solubility of Cr in Cu [23].…”

Copper passivation by metal doping

“…These include the thin film deposition [10], the passivation by thin ceramic/glass layer [3], self-assembled monolayer [11] or noble metal layer [12][13][14] and, recently, also adding minor amounts of alloying elements such as Al, Mg and Cr to copper during the metal preparation [15]. In these alloys, an impurity-rich layer is formed on the surface of copper which reduces the metal oxidation rate [16,17]. The surface segregation of the dopant atoms, spontaneous or induced by oxygen adsorption, plays a key role in preventing metal oxidation.…”

Corrosion resistance enhancement of SAE 1020 steel after Chromium implantation by nitrogen ion recoil

“…As the presence of Chromium (Cr), in excess of 12%-13% in Fe alloys, turns them resistant to several corrosive attacks, we tried to introduce Cr into the surface of this steel in such amounts. Cr films were deposited by electron beam on SAE 1020 surface and then bombarding either by nitrogen Plasma Immersion Ion Implantation (PIII) or ion beam (IB), Cr atoms are recoil introduced into the steel matrix 4,5 .…”
