Abstract
Based on analysis of test results and literature data, a phenomenological model of components interaction in Li[Ca]–V[O] system is proposed. The model demonstrates a cyclic process. Each cycle consists of: I – oxygen transfer from vanadium into lithium; II – CaO layer grows and simultaneously titanium oxides dissolve and oxygen and titanium spreading into solid solution; III – liquid metal penetration into solid metal according to the mechanism of reactionary diffusion accompanied by triple oxide formation; IV – decay of a meta-stable triple oxide and recovering of CaO layer. Within the framework of the proposed model the possible behavior of a CaO coating under isothermal condition is considered.
