Abstract
A method and a turbine part having a coating with a matrix layer that includes a high temperature resistant hydrophobic polysiloxane filler, wherein the coating has superior mechanical strength and temperature resistance.
Claims14
A coating for axially rotating machine part that in use is subject to water laden gas, the coating having a metal matrix comprising polysiloxane filler distributed throughout a thickness of the coating.
The coating of claim 6 wherein the particles have a size distribution as measured by laser diffraction of d10=0.37 micrometres, D50=1.07 micrometres and D90=2.31 micrometres.
A method for coating a part for an axially rotating machine with an erosion resilience and coating, the method comprising:
- providing a part of an axially rotating machine;
- coating the part with a coating comprising a metal matrix with a polysiloxane filler distributed throughout a thickness of the metal matrix;
- and
- stoving the filler to as to change the temperature resistance of the polysiloxane filler.
