METHOD OF PRODUCING CERAMIC REFRACTORY COAT Russian patent published in 2012 - IPC C23C30/00 C23C14/06 

FIELD: machine building.

SUBSTANCE: refractory sub layer is applied on gas turbine engine vanes, then reinforced ceramic layer is formed. Note here that said reinforced ceramic layer is formed step-by-step in the following order. Discrete layer of ceramic material in the form of insular areas on sublayer surface leaving exposed 4-98% of its total surface, at least on solid metal layer from refractory material with thickness varying from 1 mcm to 12 mcm, and outer solid ceramic layer. Discrete layer is formed from round, oval or cellular insular sites with sizes varying from 0.02 mm to 5 mm. Material of said discrete ceramic layer and outer ceramic layer may be ZrO₂-Y₂O₃ taking in the following amount: Y₂O₃ - 5-9 wt % , ZrO₂ making the rest.

EFFECT: better operating properties, reduced labor input, higher cyclic durability and strength.
