Optical Coatings

Optical coatings are used for numerous applications in commercial and technical settings, while also popular in consumer goods. At HAMR, we have experience designing, simulating, fabricating, and iterating optical coatings to satisfy customer needs. Anti-reflection coatings, filters, limiters, and gratings can be tailored for applications ranging from eye safety, asset protection, multiplexing, free-space communication, and high efficiency solar panels.

Capabilities and concepts include:

• Tailored HEL optical limiters (OLs)

• Optical coating design and optimization services and software

• Optical performance simulations (T, R, A spectra, non-linear effects, group velocity, dispersion, polarization, QA effects, etc.)

Thermal and Environmental Barrier Coatings

With target temperatures as high as 1648°C (3000°F), the next-generation of turbine hot-section components require a dramatic improvement in thermal and environmental protection. HAMR Industries has utilized a dual-pronged computational and experimental approach to design and develop new compositions and architectures, including CMAS resistant toughened composite TBCs with demonstrated performance at 1425°C. In a DoE SBIR program, HAMR extended their work into an all-oxide EBC which demonstrated significant improvements in oxidation and adhesion in 1300°C wet-cycling environments over state of the art rare earth disilicate/silicon/silicon carbide system.

Capabilities and concepts include:

• Advanced TBC, EBC, and T-EBC compositions and architectures

• Coating performance simulations (thermal conductivity, effective modulus, particle impact behavior, thermal cycling)

Cold Spray Overlays and Repairs

Cold spray is uniquely positioned as both an additive manufacturing tool and a technique capable of repairing existing components. At HAMR, our goal is to develop and certify the cold spray process for new applications and solve challenging problems such as spent nuclear fuel storage, aging domestic infrastructure, the worldwide $2.5T corrosion problem, and scaling to large format metal AM. Current work has demonstrated excellent performance of cold spray repairs for simulated spent nuclear fuel canister environments which can be leveraged for general corrosion repair throughout the energy and industrial sectors, particularly oil & gas and chemical manufacturing.

Capabilities and concepts include:

• Custom component repair and fabrication (Select Al, Fe, Ni, Cu, Co, and Sn-based alloys)

• Process and materials development

• Process and performance simulations (splat deformation and deposition modeling, coating performance, fatigue, etc.)
