Abstract (en)
The coating system for a component of a gas turbine engine comprises a bond coat BC layer (2) and a thermal barrier coating TBC layer (3) above the BC layer (2) . The BC layer (2) has a thickness in the range 180-300 micrometers and a roughness Ra of its surface facing the TBC layer (3) in a range 12.8-19.0 micrometers. The TBC layer (3) has a thickness in the range 200-700 micrometers and a porosity in the range 15.0-23.0 vol %. The ends of ranges are included in the ranges.
