Contact Melting of Metals Explained via the Theory of Quasi-Liquid Layer

It has been shown that the contact melting rate for metals is determined by the fact that at least one of them has a quasi-liquid layer on the surface. As a result, the diffusion of metal atoms occurs in the liquid phase, and not in the solid phase, which determines the characteristic contact melting time (seconds and minutes).

Automated summary

The contact melting rate for metals is determined by the presence of a quasi-liquid layer on the surface, leading to diffusion of metal atoms in the liquid phase rather than the solid phase, which affects the characteristic contact melting time.
