The method of autocatalytic reduction coating assures a precise reproduction of the coated surface. This is an advantage when the support surface has a complex geometry but also becomes a disadvantage because it requires a support without surface def

The excess of emulsion used in the lamination process leads to the formation of drops which in the annealing process forms spots of burned emulsion. It was also shown to cause formation areas with high carbon concentrations on the surface of the stee
