Abstract: An apparatus for in-situ application of an engineering coating to components has a head section for applying the engineering coating and a multi-part body section for controlling the application process. The body section has a first body member, a second body member, and a third body member interconnected with each other. The first body member has a pre-determined pathway that guides movement and is connected to the head section. The second body member is engaged with the first body member and has at least one hollow channel. The third body member houses an actuator, an engagement pin for connecting with the pathway, and at least one coupling member for interacting with the at least one hollow channel. The actuator ensures precise movement of the head section. The apparatus has one or more gas channels to provide necessary gases to the head section.

Abstract: An apparatus for in-situ application of an engineering coating to one or more components. The apparatus has a head section adapted to selectively apply the engineering coating to the components. The head section has an applicator end and a coupling end opposite to the applicator end. The apparatus has a body section coupled to the head section at the coupling end and adapted to actuate the head section. The body section has a first stage actuator adapted to actuate the head section to swivel about a first axis and a second stage actuator adapted to actuate the head section and the first stage actuator together to rotate about a second axis. The second axis is orthogonal to the first axis. The apparatus has one or more gas channels provided along the body section to the head section.
