Repair of a coating on a turbine component

摘要

A method is provided for repairing an area (30) of damaged coating on a component of a turbine module in a gas turbine engine, the component formed of a base material having a diffusion coating applied to the base material. The repair may be accomplished in place by directly heating the area to which a touch-up coating material (50) has been applied with a hot gas plasma without the need to place the component in an oven for curing and heat treatment of the touch-up coating (50) applied to the damaged area (30).
