Need inorganic sealant after HVOF process

We are doing HVOF refurbishing for the local industries. Sometimes it is necessary to heat treat the work piece after coating process. To better protect the coating material, we would like to use sealant(inorganic) to cover the surface. Please advice how can we choose these kind of materials.

Thanks in advance and best regards,

It has been my experience that anything on a part will cause the part to be considerably more ugly than if it were a clean part. You should look into vacuum furnaces or inert atmosphere furnaces.
