Patent ID: 8091366

Claim:
A gas turbine machine having a first and second machine component positioned adjacent to one another and subject to wear as a result of contact between the components during operation of the machine, comprising: a base body for the first component having an inner surface that exposed to combustion gas flows and outer surface; and a base body for the second component having an inner and outer surface; a cladding material arranged on a section of the inner surface of the base body of the first machine component and having a greater hardness than a base material of the first machine component thereby reducing wear of the first component resulting from contact with the second machine component; a cladding material arranged on a section of the outer surface of the base body of the second machine thereby reducing wear resulting from contact with the first machine component; wherein the cladding material on each of the first and second machine components is segmented and formed from a plurality of cladding segments and spaced apart from one another, with a clad segments on the inner surface of the first machine component arranged adjacent to clad segments on the outer surface of the second machine component, and the cladding material of the first machine component has a different hardness than the cladding material of the second machine component.
