Methods and apparatus for manufacturing a component

摘要

A method for manufacturing a machine component (100) is provided. The method includes forming a machine component substrate (102) wherein the substrate has a substrate surface region (104). The method further includes forming at least one primary thermal barrier layer (105) including a first ceramic thermal barrier material having a first porosity. The method also includes forming at least one secondary thermal barrier layer (107) formed over at least a portion of the plurality of primary thermal barrier layers. Also, the secondary thermal barrier layer further includes a second ceramic thermal barrier material having a second porosity that is greater than the first porosity. The method also includes forming at least one tertiary thermal barrier layer (114) comprising a smooth coat material, wherein the tertiary thermal barrier layer is formed over at least a portion of the secondary thermal barrier layer. The secondary thermal barrier layer facilitates reducing a delamination of the tertiary thermal barrier layer.
