Metals


 

Cerablak™ surface treatments can be applied to a variety of metals and alloys to prevent corrosion, oxidation, fouling, and a range of adverse degradation processes. Functional enhancements to metal surfaces can be enabled with the use of Cerablak™ treatments. Due to the phosphate-based chemistry, excellent adhesion is achieved on most metal substrates. Outstanding protection against oxidation and corrosion have been demonstrated for a wide variety of alloys. Cerablak® surface treatments also improve surface roughness and lower surface energies to promote non-stick properties at high temperatures, which is critical to many applications, including oil and gas refining, chemicals processing, or even household ovens. Cerablak® can be applied to components during production or in the field, and can be applied to geometries from simple flat surfaces to complex pipe arrangement inner and outer diameter surfaces using standard application methods such as spray, dip, flow, or spin coating.

Demonstrations


Thermally-Stable Ultra Smooth Films: Microscale roughness on metal surfaces can result in accelerated environmental degradation at elevated temperatures. Maintaining high-quality surface finishes in harsh environments is one of several benefits offered by Cerablak® UTF products.

 

Protection of Aluminum Alloys: Aluminum alloys treated with Cerablak® UTF show excellent protection against salt corrosion while preserving the reflective quality of aluminum surface through tarnish reduction.

 

Oxidation Protection of Superalloys (above): Cerablak® UTF is highly effective in providing oxidation protection to advanced steels and nickel-based alloys.  Controlling early-stage kinetics has long-term impact as shown in the example below in thermal cycling studies conducted by NASA on Cerablak® UTF-coated nickel-based superalloy.

 

High Emissivity Surfaces: A spray application process has been developed to deposit 1-5mils-thick high-emissivity coating on metal surfaces to aid in thermal management.  Cerablak® HTP is a specially-designed high-emissivity coating that is CTE-matched for many alloys and can help provide corrosion protection while effectively blocking radiant heat, up to 1200°C.
