Aerospace Coatings for Extreme Thermal Environments
From turbine hot sections to hypersonic leading edges, DRS delivers chrome-free coating solutions that meet the demands of modern aerospace programs.
Aerospace Coating Challenges
Turbine Degradation
Hot section components face combined oxidation, sulfidation, and erosion above 1000°C. Conventional TBC systems approach their performance limits in next-generation engine designs.
Hypersonic Survivability
Hypersonic vehicles require surface protection above 1400°C with low thermal mass. Standard ceramic systems cannot maintain structural integrity at these temperatures.
Weight Penalties
Bulk alloy solutions add unacceptable weight in flight-critical structures. Thin coating approaches must deliver equivalent protection at a fraction of the mass.
Chrome Restrictions
REACH and MIL-spec compliance increasingly prohibits hexavalent chromium in aerospace supply chains. Chrome-free alternatives must match or exceed hard chrome performance.
Why DRS for Aerospace
Oxidation resistance capability — enabling next-generation turbine operating temperatures.
Validated thermal cycles without spallation — proven in turbine platform environments.
Typical coating thickness — minimal weight impact on flight-critical structures.
Fully compliant with REACH and environmental mandates — no hexavalent chromium.
