摘要： Prior to instrumenting a turbine wheel for component and developmental testing, a protective coating is applied to the turbine wheel so that sensors can be welded to the coating rather than to the base material of the turbine wheel. But it is important to prevent the dovetail slots, which are critical to the usable life of the turbine wheel, from being coated. Plugs are provided that can be inserted into the dovetail slots prior to applying the coating. Each plug is shaped to match the shape profile of the dovetail slot. The plug prevents critical areas from being coated, removes the need for post processing, and allows a single coating to be applied.
