1. A seal system comprising:
a ceramic component having a first surface region defining a first surface roughness;
a metallic component situated adjacent the first surface region;
a silicon-containing layer on the first surface region of the ceramic component, the silicon-containing layer having a contact surface defining a second surface roughness that is less than the first surface roughness; and
a barrier layer on the metallic component and in contact with the silicon-containing layer, the barrier layer including an oxide and being a monolayer, the silicon-containing layer having a first thickness, the barrier layer having a second thickness, the first thickness being greater than the second thickness, and the barrier layer limiting interaction between silicon of the silicon-containing layer and elements of the metallic component.
