REPAIR OF HPT SHROUDS WITH SINTERED PREFORMS |
摘要 |
<p>A method for repairing a gas turbine stationary flowpath shroud. The method comprises providing a superalloy gas turbine stationary flowpath shroud that has previously been in service. The method further comprises preparing a restoration coating for application to the flowpath surface of the shroud by the steps of providing a precursor mixture comprising a higher-melting-point alloy component, a lower--melting-point alloy component, and a fugitive binder. A perform is prepared from the components and pre-sintered into a mildly curved form. The partially densified perform is applied to the flowpath surface and thermally bonded to the flowpath surface, forming a restoration coating.</p> |
