Metallic coating process for combustor panels using a barrel configuration

A gas turbine component comprising:

• an aluminum containing bond coat alloy formed on the gas turbine engine component by a thermal spray coating process on a clean substrate surface by:
• providing a rotatable mounting fixture comprising:
• a base attachment fixture having an axis that defines a rotation axis for the rotatable mounting fixture;
• and
• a rotatable plate attached to the base attachment fixture and oriented perpendicular to the rotation axis, wherein the rotatable plate has a circular shape with a circumference and is configured to rotate around the rotation axis;
• attaching the component to a support that is configured to hold a plurality of components attached lengthwise along the support, wherein the component is a combustor liner and the support comprises a linear T bar with a mounting plate attached lengthwise along the support, wherein the mounting plate is configured to accommodate attachment features of the combustor liner;
• placing a base of the support into one of a plurality of cylindrical tubes mounted to a periphery of the rotatable plate of the rotatable mounting fixture opposite the based attachment fixture, wherein an axis of each of the plurality of cylindrical tubes is parallel to the rotation axis, wherein placing the base of the support into one of the plurality of cylindrical tubes results in the combustor liner extending outside the circumference of the rotatable plate and capable of rotating with the rotatable plate around the rotation axis;
• transporting the fixture with the component into a coating chamber wherein a direction of an exit stream of a coater is oriented perpendicularly to the rotation axis;
• exposing the fixture and the component to a reverse transfer arc cleaning process while the rotatable plate is rotating at a first rotational angular velocity for a first time period during which the component is heated to a first temperature;
• exposing the rotatable mounting fixture and the component to a coating process during which a coating is directed at the component in a direction perpendicular to the rotation axis while the rotatable plate is rotating at a second angular velocity and is maintained at a second temperature for a second time period;
• transporting the rotatable mounting fixture with the component to a cooling chamber;
• and
• removing the component from the support.
