Our proprietary detonation gun (D-Gun) thermal spray process is the leading solution for parts that require extraordinary wear and mechanical properties. It combines gas and powder in controlled detonations to generate outstanding bond strength and density. Typical applications include fan blade midspans in aviation engines, turbine blade z-notches, knife-edge seals in power generation, steel-sheet roller guides and extruders.
Our proprietary Super D-Gun™ application detonates particles at extremely high velocities, exceeding 3,000 feet per second. And when compared to other thermal spray applications, it offers significantly improved coating properties, such as fatigue resistance. Typical applications include both original equipment manufacturing (OEM) and restoration fan blade midspans and aero-engine compressor blades.
Standard production coatings include carbides such as tungsten carbide or chrome carbide with a variety of metallic binders; metallic alloys such as MCrAlYs; and ceramics such as alumina- or yttria-stabilized zirconia and cermets, which are available in virtually any oxide/carbide/metallic ratio desired.
