Abstract:
An environmental barrier coating comprises at least one transition layer made from a transition layer slurry comprising from about 1 wt % to about 99.9 wt % water, from about 0.1 wt % to about 72 wt % primary transition material, from about 0.1 wt % to about 25 wt % slurry sintering aid, optionally, any one or more of an outer layer made from an outer layer slurry comprising from about 1 wt % to about 99.9 wt % water and from about 0.1 wt % to about 72 wt % primary outer material, and a compliant layer made from a compliant layer slurry comprising from about 1 wt % to about 99.9 wt % water and from about 0.1 wt % to about 72 wt % primary compliant material.
