Protective coatings are described herein. Embodiments of these coatings comprise substantially only specific equilibrium phases therein, and have a CTE that is substantially equal to the CTE of the substrate upon which the coating is deposited. The desired coatings can be obtained by controlling the application of the coating and/or by heat treating the coated substrate to create the desired phases or microstructure in the coating.

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 and a bond coat that is disposed on the substrate. With the workpiece at the preheat temperature, deposition of a barrier layer onto the bond coat is commenced. The barrier layer includes a rare earth silicate material having a rare earth element selected from lanthanide series elements, yttrium, scandium and combinations thereof.
Method For Applying A Barrier Layer To A Silicon Based Substrate
These things are never as seamless as they seem, said Thomas Lawton, a professor of business administration at Dartmouth Colleges Tuck School of business. There will probably be some initial teething problems.
