Engineering Coatings for Extreme Environments
RHEA thermal spray coatings that outperform conventional solutions where temperatures exceed 1000°C, corrosion is relentless, and failure is not an option.
From Lab to Field — A Four-Phase Engineering Approach
Every DRS coating system follows a rigorous development pathway from composition design through field validation.
Material Design
HEA composition optimization using phase prediction models, thermodynamic calculations, and targeted property selection for specific operating environments.
Process Development
HVOF and plasma spray parameter optimization to achieve target porosity (<2%), adhesion (>70 MPa), and microstructural uniformity across complex geometries.
Component Qualification
Full mechanical, thermal, and corrosion testing against application-specific standards. Documentation packages for aerospace and nuclear qualification pathways.
Field Deployment
Transition from lab-scale to production coating with process control documentation, operator training, and ongoing technical support through service life.
What Makes DRS Different
Three interlocking capabilities that no conventional coating vendor can match.
RHEA Coatings
Multi-principal-element alloys combining Mo, W, Ta, Nb, and Re in optimized ratios. Single-phase or dual-phase microstructures engineered for target combinations of hardness, oxidation resistance, and thermal stability at temperatures exceeding 1800°C.
Precision Thermal Spray
High-velocity oxy-fuel and plasma spray processes optimized for thick alloy layers (>5mm), multilayer architectures, and internal diameter geometries down to 12mm bore diameter. Porosity consistently below 2%.
Application-Driven R&D
DOE, MDA, and USAF funded research programs translate fundamental HEA science into deployable coating systems. Six government grant awards spanning 2012–2023 validate our technical approach.
Built for the World's Hardest Operating Environments
Validated across the most demanding industrial sectors where coating failure has mission-critical consequences.
Nuclear / MSR
Fluoride salt corrosion resistance at 700°C. Tritium containment coatings for next-gen molten salt reactors.
Aerospace
TBC systems surviving 1400°C and 500+ thermal cycles. Chrome-free alternatives for REACH compliance.
Defense
Hypersonic vehicle TBCs exceeding 1800°C. Erosion-resistant coatings for gun barrels and rocket nozzles.
Industrial
15,000-hour validated service life in hot corrosion environments. 4.2× service life extension vs. conventional coatings.
