摘要: 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.

摘要: A composite comprising a silicon based substrate, an environmental barrier coating (EBC) with a top layer, wherein the top layer comprises a velocity barrier layer. Velocity barrier layer is any layer positioned between a flowing gas stream and the underlying EBC protective layer which acts to reduce the velocity of the gas stream which otherwise would impinge on the underlying protective layer.

摘要: An article comprises a silicon based substrate, a bond layer and a protective top layer. The top layer is selected from the group consisting of rare earth disilicates, yttrium disilicates, rare earth monosilicates, yttrium monosilicates, silica and mixtures thereof. The protective layer described above is used in combination with a bond layer provided between the protective layer and the silicon based substrate which functions as oxygen getter and includes an oxygen gettering agent. By oxygen gettering agent is meant a refractory metal oxide former which forms an oxide at operational condition of (high temperature and aqueous environment) having a melting point of greater than 1500° C. wherein the negative free energy of formation of the refractory metal oxide from the refractory metal is more than 100 Kcal/mole. Suitable oxygen gettering agents include silicon and other refractory metals. An oxygen gettering agent may also be added to the protective layer.
