ENGINEERED COATINGS: ADDING MORE VALUE, OPTIMIZING PERFORMANCE
Today the search for a better mousetrap doesn’t end where it used to. Design engineers are pushing the envelope even further with engineered surface treatments to create products that perform like never before.
No wonder the latest engineered coatings are found everywhere: delivering greater thermal protection in a new generation of jet engines, adding thousands of hours to the life of wear parts in harvesting equipment, right down to the electrical insulation on a surgeon’s scissors. Finding and applying the optimum coating for applications in hundreds of challenging environments isn’t for the faint of heart – so start with the best: TST® Engineered Coating Solutions from Fisher Barton.
Ready to take your product to an entirely new level? Fisher Barton has the thermal spray technologies and materials expertise’ to optimize your parts, components, and structures and ‘materialize’ new coatings solutions that add exceptional value.
Our expertise enables us to engineer the perfect coating for nearly any application. There are multiple types of Coating Solutions and we can help you engineer and apply the right one for your specific parts components, structures, or equipment application.
Our coatings are engineered specifically for each application through the utilization of our expertise in materials engineering. Most of our coatings are supplied to original equipment manufacturers (OEM’s), on new components produced in medium to high volumes.
Wear Resistant Coatings
No single coatings solution can solve all the many surface wear challenges that result from erosion, abrasion, adhesion, cavitation and corrosion. Chances are, we’ve seen it, and solved it, before. We are expert in:
- Carbide coatings in the form of cermets (ceramic and metal) to provide exceptional hardness and wear resistance.
- Tungsten carbide, to achieve exceptionally high hardness levels and resistance to extreme temperatures and corrosion.
- Metal oxides such as chromium oxide are very hard and exceptionally resistant to chemical attack; an ideal solution for both wear and corrosion.
- A variety of other metals and even some plastics to provide wear resistant coatings.
When engineering wear resistant coatings, we use our strong expertise in materials engineering and the wear resistant properties of various materials and deposition methodologies. The combination of this knowledge provides application specific solutions to our customers wear problems.
Highly complex components, such as jet engine compressor blades, are coated for wear resistance. Even simple parts, such as bolts used in agriculture combines are coated with carbide coatings to greatly extend the life of the bolts and prevent machine damage from the detachment of high speed rotating parts.
Corrosion Resistant/Protective Coatings
For countless applications where materials such as iron and steel alloys are used and paint alone isn’t up to the job, corrosion protection has never been more critical. When working with our technical staff on corrosion prevention solutions, it is very important to understand the environment in which the component is exposed. Our materials engineers use that information to create a corrosion protective coating solution specific to that component’s requirements. Our expertise in understanding materials properties and various coating processes will be used to select the best deposition methodology and optimum process parameters. Our coatings include:
- Galvanic corrosion prevention coatings: made from materials such as iron and steel alloys. These coatings slowly corrode while minimizing the corrosion occurring to the steel.
- Corrosion resistant coatings: Made with nickel-chromium and cobalt-chromium alloys, delivering very low porosity levels.
- Wear and corrosion resistant coatings: Cermet materials (ceramic and metal) such as carbides with corrosion resistant metal binders provide both corrosion and wear protection. Oxide ceramics are an option as well, with very hard and corrosion resistant properties.
We’re the industry’s best source for dielectric coatings with high bond and dielectric strengths, exceptional hardness and very low porosity. Our coatings have high bond strengths and features less than 0.1% porosity creating a theoretically dense layer with dielectric strength up to 1,000 volts/mil or greater, and typical hardness of 1,000 dph/ Vickers. These include:
- Dielectric coating materials: The most common are oxide ceramics and polymers. Ceramics are more durable, wear and corrosion resistant, and have higher dielectric strengths than polymers.
- Substrate materials: Application to almost any metallic substrate as well as composites. For high temperature applications, gradated coatings are used to mitigate differential expansion between the substrate and the dielectric coating.
- Super finishing: Our dielectric coatings can be super finished for a surface roughness (Ra) even less than four micro inches.
Our dielectric coatings are used for high and low voltage applications over the range of DC to RF. They can be applied to an almost limitless number of materials, enabling us to produce dielectric coatings to solve even the most complex electrical challenges.
TST fixturing, tooling, and cell design for dielectric coatings are specially engineered. Are unique materials, parameters, and equipment enable us to produce high-quality dielectric coatings at high production volumes.
Electrically Conductive Coatings
Where electrical conductivity is required, we apply our extensive materials and deposition expertise to custom-engineered coating solutions, factoring in operating temperatures, environment, and life cycle requirements.
- Coating materials: Materials such as copper, aluminum, and molybdenum are often used, providing the required degree of electrical conductivity. Solutions for high-temperature applications include iron-chrome-aluminum and molybdenum-disilicide.
- Substrate materials: Applicable to everything from polymers and composites to ceramics; all designed for various power levels and coating/substrate interactions under power and at temperature.
When engineering an electrically conductive coating we use our extensive materials engineering expertise and understanding the deposition methodology to provide effective custom engineering coating solutions. Operating temperatures, environmental medium, and lifecycle requirements are just a few of the considerations for developing an effective solution for electrical conductivity. The combination of this knowledge provides application-specific solutions to our customers’ electrical design issues.
Conductive Coatings can and have been used to create heating elements, slip rings, static dissipative elements, ground straps, flexible circuits, in situ thermocouples, commutator segments, contact points for silicon carbide heating elements, and much more.
A Fisher Barton proprietary process, FluxFuse minimizes distortion and warping of components found in typical open-air fusing, while providing consistent, uniform fusing conditions for adhering thermal spray wear coatings to the component base material.
Superior fusing of a wear coating results in a much stronger coating bond and, ultimately, increased wear component performance and durability. Combining Fisher Barton’s patented MARBAIN® base material with FluxFuse combines the best of the materials and coatings worlds, offering a world of new opportunities for longer life and improved performance.

A TST proprietary post coating heat treatment done in controlled atmosphere to promote coating diffusion into the coated component to create a metallurgical bond and promote diffusion within the coating almost eliminate coating porosity. The FUSION bonded coating with its tenacious metallurgical bond can withstand high impact, and the high-density coating provides enhanced wear and corrosion resistance.
Just like the diverse array of deposition methodologies, so to are the types of materials that can be used to produce Coatings, and the materials onto which Coatings can be deposited.
At TST we have the philosophy that the imagination is the only limitation to what can be produced.
Almost all metals can be coated. Many plastics can also be coated, especially plastics that have a higher melting range. Some deposition methodologies can generate temperatures as high as 30,000 degrees Fahrenheit (>16,500 C). Very high melting point materials can be applied such as oxide Ceramics. In general, if a material melts there is a good chance the material can be used to create a coating.
Parts you don’t think can be coated due to our expertise in materials, and the process can commonly provide coatings on substrate materials that you just don’t think can be coded. From plastics to carbon fiber to glass if you have a difficult substrate material
