SAMPLE HFPD COATINGS
METALS, CERAMICS AND CERMETS
Note: Three patent pending coating applications (MCrAlY, YSZ and cermet related) are available for licensing.
OVERALL ATTRIBUTES OF COATINGS AND SYSTEM
Very Versatile
o Wide choice of processing gases
o Sprays most powders—from metals to ceramics
o Low thermal input—able to spray heat sensitive substrates and geometries
o Pathway to new proprietary coatings’ development (see following sample coating benefits) due to the novel characteristics of this pulsed technology (frequencies of 1 to 100 Hertz) and its recent introduction to the marketEconomical
o High deposition rates
o Low consumables
o Essentially zero maintenance and repair times due to state-of-the-art completely digital control system and modular construction
o Low spare parts costs because no moving parts
o Single person operation
Safe and Easy
o Fail-safe fuel control/mixing design
o Half-day set-up and training
o Fast change over—typically 15 minutes or less
