Nexceris has developed coating technologies for metallic and ceramic substrates to address materials issues in high temperature systems. We provide a range of functional coatings for electrical, corrosion and catalytic applications using scalable, cost effective processes. Leveraging a portfolio of intellectual property and manufacturing know-how, we help our customers create products that perform better, simplify operations and save money. Nexceris provides coating suspensions, coating services and process development services to customers around the globe.
While other corrosion protection methods (silica- or alumina-forming alloys) create oxidation resistant surfaces, contact resistance is increased. ChromLokTM surfaces remain electrically conducting for years under harsh temperature conditions.

Nexceris’s ChromLokTM system provides metallic components used in solid oxide fuel cell (SOFC) systems with the high temperature protection they require. The ChromLokTM system includes a range of complementary oxide coatings that prevent the release of detrimental chromium species from stainless steels during high temperature operation. Coatings include a manganese cobaltite (MCO) coating, which combines excellent protection with low resistance and is ideal for the cathode active area where electrical conductivity is critical. An additional coating for the non-active area of the interconnect is also available.
Nexceris’ AlumiLokTM coating process is a scalable, cost-effective approach to protect metal components from corrosion in high-temperature applications. Coated stainless steel components exhibit eight to ten times less oxidation, greatly exceeding the performance of other high temperature alloys. AlumiLokTM has been shown to work with a wide range of materials, including ferritic & austenitic stainless steels, Inconel, nickel alloys & copper alloys. AlumiLokTM replicates the traditional aluminization surface microstructure, proving just as effective as the expensive vapor phase aluminization process.
Nexceris’s sales division, fuelcellmaterials.com offers coatings using the ChromlokTM and Alumi-LokTM materials systems. Coating services are offered for a wide range of component shapes and sizes, with masking and/or multiple coating compositions. We provide coatings under spot buy and blanket contract agreements.
