Composite article having silicate barrier layer and method therefor |
摘要 |
A method of processing a composite article includes controlling a preheat temperature of a workpiece to be less than 700°C/1292°F. The workpiece includes a substrate (22) and a bond coat (24) that is disposed on the substrate (22). With the workpiece at the preheat temperature, deposition of a barrier layer (28) onto the bond coat (24) is commenced. The barrier layer (28) includes a rare earth silicate material having a rare earth element selected from lanthanide series elements, yttrium, scandium and combinations thereof. |
