Regular ArticleReaction diffusion rate coefficient derivation by isothermal heat treatment in spark plasma sintering system
Graphical abstract
The reaction diffusion rate coefficient K for the CuTi and Cu4Ti phases, derived using an approach involving isothermal heat treatment of pulsed electric current (PEC) generated in spark plasma sintering system, is at least two times higher than the corresponding ones determined under conventional annealing (CA) treatment.

Conversely, in the SPS process (Fig. 14b1 and b2), the interfacial healing of the BNNSs/Cu coating is a result of multiple physical fields, including electric current, electric field, thermal field, and stress [43,69]. Such multiple physical fields promote the destruction of the oxide layer, the cleaning of the nanosheet surface and the diffusion of oxide atoms so that an infiltration interface can be formed [34].
