Carburization


Performance of metal/alloy surfaces in fuel-rich or hydrogen or reducing environments at elevated temperatures is highly critical. High-temperature-stable Cerablak® UTF offers lasting fouling and corrosion protection without reducing heat transfer capabilities. Cerablak® surface treatments can be applied to both external and internal surfaces of many different materials, and can often be applied to fully-assembled process component designs and structures.

 

Carbon Deposits Reduce Material Performance and Lifetime
Carburization refers to the formation of carbides in common processing alloys such as steel, and is the result of exposure to a carbon-containing atmosphere at high temperatures. It can degrade mechanical properties over time and materials must be replaced more often. "Metal dusting" is one example of a carburization process which results in surface attack and the formation of a residue that reduces process efficiency. Carburizing environments are commonly found in process piping and furnace tubes of carbon-containing species in the petrochemical industry and other industrial processes. Fouling on process equipment resulting from metal dusting, carburization, and coking is a universal and longstanding problem across many industrial production applications.

 

Cerablak® UTF Protects from Carbon Buildup
Cerablak® UTF can be applied to nearly any metal surface using a solution process. It can be applied to pipe inner diameters and acts as a thermally stable barrier to carbon-containing gases. Due to the ultra-thin nature of Cerablak® UTF, thermal shock resistance is excellent—the film can withstand severe thermal cycling.   Under reducing conditions, Cerablak® UTF remains stable for over 1,000 hours at elevated temperatures to provide long-term protection.
