<p>COATING APPARATUS AND METHODS A coating end effector may be carried by a robot. A plasma spray head is mounted by a joint to the end effector. A plurality of actuators couple the end effector and plasma spray head to provide articulation of the joint. The apparatus may be used to coat an airfoil cluster of a gas turbine engine. The coating may include passing the head between the airfoils.</p> |
