Abstract
Methods for forming a sintered bond coat () on a silicon-based substrate () and articles () formed by the methods are disclosed. The methods include applying a bond coat slurry on the silicon-based substrate (), drying the bond coat slurry on the silicon-based substrate to form a dried bond coat (), and sintering the dried bond coat () in an oxidizing atmosphere to form a sintered bond coat () on the silicon-based substrate (). The bond coat slurry includes a bond coat patching material in a bond coat fluid carrier. The articles () include a silicon-based substrate (), a sintered bond coat () formed on the silicon-based substrate (), and a sintered environmental barrier coating (EBC) () formed on the sintered bond coat (). The sintered bond coat () includes a silicon-based phase and an oxide of the silicon-based phase.
