Specialized Solutions for the aerospace industry
Our custom coatings offer unparalleled resistance to many types of wear and environmental and thermal degradation, improving the functionality of your components and increasing the time between overhauls for both civil and military aircraft. From thermal barrier coatings that allow you to run your engines hotter to environmental barrier coatings that allow you to operate longer to abrasive and abradable coatings for clearance control, our diffusion, electrodeposition, engineered slurries, laser cladding, thermal spray and vapor deposition coating technologies have you covered.
Our coatings offer protection from wear, friction, corrosion, erosion and more over a wide range of temperature excursions for airframe structural components and systems such as actuators, gearboxes, wing flaps and tracks. Our low-fatigue coatings are particularly well suited for helicopter components subject to unique vibration stress.
Our variety of thermal spray and engineered slurry coatings can help you transition from hexavalent chrome and cadmium plating. We offer replacement solutions that are kinder to the environment but tougher than ever on corrosion.
Coating Services for the aerospace industry
We offer a full range of aluminide and chromide coatings utilizing SermaLoy™ and SermAlcote® slurry processes as well as pack and vapor processes. In addition to simple aluminides, we offer modified aluminides such as platinum aluminide (PtAl) coatings—a preferred coating choice for many aviation gas turbine hot section airfoils. Compared to other aluminides, these coatings provide exceptional oxidation protection and are used for many high-pressure (HP) and low-pressure (LP) turbine airfoils where additional environmental protection is required.
Our Tribomet™ electrodeposition abrasive, wear-resistant and MCrAlY coatings provide non-line-of-site coatings with precise thickness control, excellent metallurgical bonding and low porosity. Tribomet coatings provide excellent resistance to adhesive wear, abrasion, corrosion and oxidation and formulations and provide high-performance abrasive cutting capability for blade tips.
Application of our SermaLoy™ and SermeTel™ slurry coatings provides unsurpassed protection against aqueous corrosion and heat scaling, as well as erosion, abrasion and wear. We apply our slurry coatings by brushing, flowing, dipping or spraying onto clean prepared surfaces. And because the deposition process is relatively gentle, slurry coatings can be deposited not only on metals, but also on ceramics, glass and composites. Chrome-free slurry coatings that meet global environmental regulations are also available.
Our laser cladding and hard facing processes produce weld overlays that are metallurgically bonded and virtually impenetrable, resulting in reduced maintenance, repair and equipment replacement costs. Laser hardening of steel or cast iron components typically yields a 20% greater hardness than conventional heat treating.
One-Stop-Shop for Airframe
Offering you the convenience of having all your needs met in one location, our one-stop-shop services for OEMs and Tier 1 suppliers support your components from start to finish. From preparation to coating to ancillary services such as grinding and honing all the way to part marking, you can reduce repair time and get your critical components in the air efficiently by eliminating the need for multiple vendors. One-stop-shop services are available from our coating service centers in Canada, China, France, India, Italy, Korea and the United Kingdom.
Thermal Spray Coatings
Metals, alloys, carbides, oxide and non-oxide ceramics, refractory metals, cermets (ceramic-metallics) and other materials can be deposited via our cold spray; detonation gun (D-Gun or Super D-Gun™); high-velocity oxy fuel (HVOF); conventional, low-pressure or suspension plasma spray; and wire spray processes. Using a wide range of spray rates, our thermal spray coating processes can produce a wide array of coating thicknesses. Uniform coatings can be applied to parts with complex geometries, and strong bonds withstand heavy mechanical loads.
Vapor Deposition Coatings
We offer state-of-the-art electron beam physical vapor deposition (EBPVD) high-performance thermal barrier coatings for aero-engine turbine blades and vanes that are highly tolerant to lateral strain.
Our cathodic arc physical vapor deposition (CAPVD) process deposits ultra-hard wear-, corrosion- and erosion-resistant thin film coatings on precision parts. We offer titanium nitride (TiN) as a monolayer and multilayer coating.
Our chemical vapor deposition (CVD) coatings are applied in a chamber containing parts and a reacting gas at high temperature to form, by absorption or accumulation, a surface layer composed of constituents from the part and the reactive gas.
For optimal adhesion and interface cleanliness, we offer cleaning, blasting and stripping surface preparation services before coatings are applied. We also provide dimensioning, heat treating, peening and testing to maximize newly coated surfaces.
In the 1950s we began making wear-resistant coatings to help the aerospace industry be more efficient. Today our protective coatings are used on thousands of parts in most production aircraft engines and airframe structural components and systems. We understand the clearance, corrosion, oxidation, wear and thermal-related problems you encounter every day—on land or in the air. Our complete range of advanced coating services allows you to get new or refurbished equipment into production quickly, and keep it running longer. With unmatched quality and experience, we have pioneered the best-performing surface protection coatings in the industry. In fact, many of our coatings are OEM-designated protection for the most critical components in your gas turbine engines and airframes.
Products for the aerospace industry
We’ve been a leader in gas-atomized metal powders for more than 50 years. And our AM powders are not a commodity—they are a specialty. Our AM cobalt, iron, nickel and titanium powders flow easily and deposit evenly, resulting in successive layers with consistent density and uniform build rates. This helps products meet the mechanical, performance and final part specifications of the aviation industry as it manufactures 3D printed parts.
Where corrosion, oxidation, wear, insulation or release properties are critical issues, our SermeTel™ coating slurries provide protection. We offer approximately 150 active slurry compositions in the form of inorganic primers, sealers, dry film lubricants, cements, resins and other materials.
Application by application, we offer the appropriate thermal spray equipment—arc spray, gaseous-fueled high-velocity oxy fuel (HVOF), liquid-fueled high-pressure HVOF (HP/HVOF®), plasma spray, powder feeders and integrated/automated system solutions—and the right materials and parts to do the job optimally and cost effectively.
With our hundreds of standard products and our industry-leading ability to formulate custom compositions, you're sure to get the right solution for your coating needs with our powders. Our lot-to-lot consistency means you’ll have a more dependable spray process, less need for over-testing of coating quality, less waste and reduced costs.
We manufacture the highest-quality wires for thermal spray. We offer a wide variety of wire chemistries, ranging from traditional metals and metal alloys to complex cored wire compositions for demanding wear applications.
