This may be explained by the high amount of feed MB (1% w/w) which could affect the properties of the BSA matrix network, thus affecting the diffusion barrier. The slow release step of MB may occur through surface erosion of the BSA matrix.

The dissolvable solderable coating for electronics mostly consists of an adhesive layer (Cr, Ni, Ti, Al) diffusion barrier (Ni, Cr, Pt Pd) and a solderable layer (Ag, Au, Cu, Ni).

The protective effect is attributed to the formation of molten glass layer on steel surface at high temperature, which acts as an effective oxygen diffusion barrier. This glass-based protective coating by low-cost and easily handling method is potentially applicable in a slab reheating process.

Such "diffusion potentials" are expected to be present in all processes that involve diffusion of charged species due to differences in inherent ion mobility and the perm-selective nature of the diffusion barrier. Thus, the subsurface demineralization is largely diffusion-controlled, and the rate of lesion progression may be expected to depend on factors that govern the diffusion process.
