PROCEDURE FOR ITEM COATING AND ITEM Russian patent published in 2011 - IPC C23C14/14 C23C14/34 

FIELD: metallurgy.

SUBSTANCE: on base there is applied layer of aluminide modified with platinum of formula PtMAl, where M corresponds to metals iron (Fe), nickel (Ni) or cobalt (Co) or combination of these metals. A layer is created by physical sedimentation from vapour phase (PVD). At least both components, aluminium (Al) and metal (M), are physically settled from vapour phase at process pressure at least 0.1 mbar, preferably, at least 0.4 bar and, in particular, between 0.4 mbar and 0.6 mbar.

EFFECT: item manufactured by this procedure can be turbine blade.
