Self-healing electrical insulating coating processes for vanadium alloy–lithium systems

The existing technological approaches for the formation of nitride- and oxide-based self-healing electrical insulating coatings for vanadium alloy–lithium systems are considered. The results of the property study of coatings applied from liquid lithium containing Al, N, Si, B additions on various modes are considered. The formation conditions of AlN-based coatings with scale specific electrical resistivity (∼50 Ω m) on the V–4Ti–4Cr vanadium alloy are determined. The results of formation and stability research of coatings on the V–4Ti–4Cr vanadium alloy in convectional and forced circulating lithium with Al and N additions in the homogeneous and heterogeneous lithium systems are discussed.
