Applied Thermal Coatings

What Applied Thermal Coatings does

Applied Thermal Coatings, Inc. (ATC) is a privately held, minority-owned industrial services firm founded around 1997 and headquartered at 700 Manufacturers Road, Chattanooga, Tennessee. The company operates with 11 to 50 employees under founder/co-owner leadership (CEO Harley Grant) and serves enterprise customers in coal-fired and combined-cycle power generation, pulp and paper, and waste-to-energy. Its commercial model is enterprise field sales delivering specialized engineering, coatings, and inspection services either at client sites or at its Chattanooga facility.

The company's core technology stack centers on thermal spray coatings (Extendalloy nickel-based tungsten and chromium carbides applied via HVOF, plasma, twin-arc, and spray-and-fuse methods) and diffusion coatings (chromizing, aluminizing, boronizing) supported by two registered patents covering localized chromium diffusion and microwave-based metal diffusion. A separate heat-treatment division operates an extensive furnace range — from small lab units to a 35-foot push-through furnace rated to 3,000°F with hydrogen atmosphere capability — enabling quench and temper, normalizing, annealing, solution annealing, stress-relieving, PWHT, precipitation hardening, and flame hardening. These process capabilities are backed by an in-house metallurgical laboratory and a field NDE division offering phased-array ultrasonic, TOFD, TFM, and API 510/570/650/653 inspections.

ATC monetizes primarily through professional-services engagements: failure analysis, condition assessments and remaining-life calculations, fitness-for-service evaluations, welding metallurgy and qualification, structural and duct design, outage construction support, and coating application on customer-supplied components. The company is ISO 9001 certified (2024–2027 cycle), holds ASME code committee influence through Co-Owner/President/COO Jeff Henry, and collaborates with Oak Ridge National Laboratory on Grade 91 and CSEF steel development. Revenue is not publicly disclosed, and no institutional investors, parent entities, or acquisition activity are referenced in available materials.

Broad incumbents

• Haynes International: Manufacturer of high-performance nickel- and cobalt-based alloys used in high-temperature and corrosive environments that overlap with the application space where ATC's coatings protect base materials. Adjacent rather than directly competing on coating services.
• Curtiss-Wright Surface Technologies: Division of Curtiss-Wright providing thermal spray, coatings, and surface treatment services for aerospace, defense, and industrial markets. Comparable in service type to ATC but serves much broader end markets with a global footprint.
• Praxair Surface Technologies (Linde): Operates one of the largest thermal spray and coatings application networks globally as part of Linde. Overlaps with ATC's thermal spray and diffusion coating services but at vastly greater scale and breadth across aerospace, industrial, and energy.

Regional players

• Wallwork Heat Treatment: U.K.-based commercial heat treatment and vacuum processing provider with deep service overlap to ATC's heat treatment offering, but operating in a different geography and serving primarily European industrial customers.
• Solar Atmospheres: U.S.-based commercial heat treatment specialist operating large vacuum and atmosphere furnaces for aerospace and industrial customers. Comparable to ATC's heat treatment capabilities and capital-intensive furnace model, with stronger aerospace exposure.

Direct peers

• Progressive Surface: Manufacturer and applicator of thermal spray coatings (HVOF, plasma, twin-arc) for industrial components. Comparable to ATC's thermal spray process capability and end markets in power and heavy industry.
• ASB Industries: U.S.-based thermal spray and coatings applicator offering HVOF, plasma, and twin-arc spray services for industrial components. Comparable to ATC's Extendalloy thermal spray offering and similar power-generation/customer base.
• A&A Thermal Spray: Specialty thermal spray coatings provider serving industrial and power-generation customers with HVOF, plasma, and flame spray processes. Directly comparable to ATC's Extendalloy thermal spray service line.
• Bodycote: World's largest commercial heat treatment and thermal processing services provider, serving aerospace, automotive, and industrial markets. Directly comparable to ATC's heat treatment and coatings service stack, though at vastly greater scale and geographic reach.

Others

• Ellwood Group: Specialty steel and engineered components producer serving heavy industrial, forging, and energy customers. Adjacent to ATC's metallurgical engineering and power-generation customer base, with overlap in failure analysis and material supply rather than coating services.
