Fe-flash in zeta phase of galvnealing coating.

Optimisation of the thickness of an Fe-flash as barrier for surface segregation and selective oxidation. Concerning the Fe-flash, the effect of thickness and heating rate was examined in detail. There is clearly a texture effect present, but it is not sufficient to reduce significantly the thickness of the flash. Logically, heating rate has a very important influence: with 50 K/s, typically for radiant tube type of furnaces, Si-diffusion cannot be hindered by a flash of 1 μm thickness. The creation of a bi-layer Ti-Fe as a barrier proved not to be successful because of adherence problems of the Fe-layer.
