Brushed, Dipped, Flowed or Sprayed Slurries


Bake in the protection

We can apply a wide range of coatings bonded to the substrate. Because the process is relatively gentle, our slurry coatings can be used on any surface capable of withstanding the thermal cycle needed to cure them—from metals to ceramics to glass. The only limit is the size of the part and its ability to fit in the oven to be cured. See the different slurry processes we offer below.

SermAlcote® Diffused Aluminide Coating -

A superior alternative to many industrial pack and vapor-phase aluminizing processes, our SermAlcote® process forms a uniform, oxidation-resistant, diffused aluminide on nickel alloys. This dip-applied slurry can help you meet common commercial process specifications for aluminide coatings, platinum-modified aluminide coatings and over-aluminized MCrAlY coatings that resist high-temperature oxidation.

Typical applications include gas turbine hot section components.

SermaGard® Composite Coatings -

Our SermaGard® composite coatings are composed of various binders combined with metallic, ceramic or thermoplastic materials. Our predominant binder system is a unique, water-based, inorganic material that cures at a low temperature to produce a ceramic bonding matrix.

Depending on the additive materials and topcoat selected, SermaGard coatings can deliver a variety of resistance combinations, including a unique capability to combat aqueous corrosion and heat. They also offer chemical, oxidation, thermal shock, wear and abrasion resistance and create superior lubricity, release and sealing characteristics.

SermaLon™ Multilayer Coatings -

The SermaLon™ coating system is our patented multilayer coating known for its unique capability to resist aqueous corrosion and fouling in gas compressors and industrial gas and steam turbine components.

SermaLoy™ Diffusion Coatings -

In the SermaLoy™ process, a slurry is applied to the component surface, then diffused. The result is an aluminide-diffusion coating that adheres tightly to the part surface and is very resistant to both low- and high-temperature hot corrosion and oxidation.

Typical applications include gas turbine hot section parts and industrial components.

SermeTelTM Inorganic Coatings -

The SermeTelTM process bonds inorganic coatings with metal substrates to form a ceramic-metallic (cermet) composite layer that provides unparalleled protection against aqueous corrosion, heat scaling, erosion, abrasion and wear.

Used on a wide variety of metal components, SermeTel coatings protect parts from continuous and intermittent exposure to corrosive salt environments, air, thermal shock conditions and extreme temperatures.
