Protective coatings for metallic Balance of Plant (BoP) components.

Our coatings are designed for high-temperature corrosion protection for steel and superalloy components.

The ChromLok™ System

ChromLok System

The ChromLok™ System is designed to enhance alloy stability and it prevents chromium volatilization. It provides metallic components used in solid-oxide fuel cell systems with the high-temperature protection they need. It includes a range of complementary oxide coatings that prevent the release of detrimental chromium species from stainless steels during high-temperature operation.

Coatings include manganese cobaltite (MCO) coating, which combines excellent protection with low resistance, ideal for the cathode active area where electrical conductivity is critical. Additional coatings include non-active, insulating coatings compatible with common seal materials and a Ni-based anode side coating.

The AlumiLok™ System

Chromlok Coatings

The Alumi-Lok™ protects metallic components from coking, corrosion, and degradation in oxidizing environments. It offers an aluminization coating to protect the non-active area of the interconnects and critical Balance of Plant parts from the effects of high-temperature corrosion. This coating is designed to be processed at the same time as the other coatings on the interconnect, ensuring an economical solution is maintained.

Catalyst Coatings

Red Catalyst 2

Our materials specialists collaboratively design custom aerosol, dip, and wash-coated catalyst coatings for catalysts synthesized by HPS or our partners.

We have decades of experience coating catalysts onto metal and ceramic substrates, monoliths, tablets, plates, and foams.
