ALUMILOK
High Temperature Corrosion Protection
The 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 Updates
Accelerated Testing for Long-Term Results with Solid Oxide Fuel Cells
To achieve commercial acceptance, long-term stability testing is critical to demonstrate improved durability of protective coatings. Nexceris has successfully developed a suite of coatings to provide improved high-temperature protection to metallic components used in solid-oxide fuel cells (SOFC).
Revisiting Nexceris’ Solid Oxide Fuel Cell Advancements from MS&T 2018
Remember MS&T 2018 in Columbus, Ohio? No?! Well, all of us at fuelcellmaterials want you to remember what we talked about and fueled up your brain a bit.
Functional SOFC Interface Coatings Presented at European SOFC & SOE Forum
Nexceris was honored to give a presentation at the 13th European SOFC & SOE Forum on our development of various SOFC interfaces created by aerosol-spray deposition. Our Director of Materials Science, Neil Kidner, recently gave a talk on July 4th at the conference, which is held every two years in beautiful Luzern, Switzerland.
