Definitions

  • the invention relates to a compressor wherein the blades of the compressor have a coating against corrosion and erosion and wherein a similar or same coating is applied on the casing of the compressor and a gas turbine.
  • Ni-Graphite abradable coating is been used to reduce the gap between the compressor blades and casing to increase the efficiency of gas turbines.
  • this coating starts rubbing, the detached coating debries start depositing on the turbine airfoils. It has been demonstrated that these deposits can induce damage of the ceramic thermal barrier coating due to alterations of its thermo-mechanical properties.
  • the figure shows one example of the invention of the compressor blade and an outer casing which are both coated.
  • the compressor 1 has an outer casing 4 and compressor blades 10, which can rotate inside the casing 4.
  • the compressor blades 10 have a coating 13 against corrosion and erosion.
  • the matrix of this coating 13 can be any coating, especially a chromate phosphates based matrix is used.
  • the coating 13 can preferably also be a bilayer made of the same material, but especially with aluminium particles in the underlying layer.
  • a tip 16 of the compressor blade 10 which faces the casing 4 is preferably also coated with the same material of the coating 13.
  • the casing 4, which faces the compressor blade 10 also has a coating 7 along the inner circumference of the casing (4), especially only applied locally opposite to the compressor blade 10, which has the similar composition especially the chromium phosphate matrix.
  • Chromate phosphate based coatings are state of the art and are shown in US 7,789,953 B2 .
