Compact, High Efficiency Plasma Spray Gunsfor Jet Engine Coatings

The design and operation of a new range of compact, high efficiency guns is described. Data is presented to show that high quality coatings are obtained using low operating power levels and that narrow spray patterns are produced.

The use of this new technology to produce coatings for jet engine components, such as, burner cans or combustion liners, turbine blade areas, and fan disc slots, is discussed.
