Abstract
The invention relates to a method for manufacturing a part (1) comprising a nickel-based monocrystalline superalloy substrate (2). This method is characterised in that it comprises the steps that consist of: manufacturing a nickel-based monocrystalline superalloy substrate (2); forming a coating (3) on said substrate (2), comprising at least one layer (30) of a first type comprising aluminum and platinum, at least one layer (31) of a second type comprising aluminium, silicon, platinum and a layer (32) of a third type comprising nickel, aluminium, silicon and platinum, said layer (32) of the third type being the outermost layer of the stack of coating layers (3); and forming a layer (4) of silicon-doped alumina on said layer (32) of the third type.
