  • Patent number: 6544589
    Abstract: A method of controlling drying stresses through controlled shrinkage of a ceramic coating coated onto a substrate. The method first includes applying a non-cured ceramic coating onto the substrate and permitting the coating to dry until a mechanically stable outer surface layer of the coating is formed. Once this layer is formed, a drying control is applied in a quantity sufficient to penetrate into the surface layer, with the result of such application being the inhibition of formation of a dry outer skin as continued drying is permitted to occur. Once such drying is complete, the outer surface layer is subjected to an elevated temperature for curing and for evaporating therefrom the drying control agent to thereby produce a cured-ceramic coated substrate whose coating is void of large cracks and whose durability is beneficially opportune.
