The Science Of Precision Coatings


Key Benefits:

  • Fully compliant to AMS 2438
  • Thin even deposit, does not require secondary machining
  • Thin deposit does not affect part tolerances, can be applied as low as .00005″
  • Increased wear resistance, high surface hardness
  • Cold process for no part distortion
  • Enhance corrosion resistance (including atmospheric corrosion), corrosion resistance equal to 400 SS
  • Extensive onsite testing and quality control
  • Absolute bond to the base metal
  • Performs in vacuum environments

Armoloy TDC® is a metallic coating process designed for high precision applications required by the Aerospace industry. Our ability to control the process without affecting tight part tolerances makes it ideal for precision applications requiring increased wear, corrosion, and lubricity properties. The thin, hard coatings can be applied at even deposits ranging from .00005″ to .0006″ per side, with tolerances ranging from 0.00025″ to .00005″ per side. Please consult your Armoloy engineer for applications requiring heavier deposit thicknesses. Armoloy TDC is considered a “cold” process that will not distort, anneal, or cause dimensional changes to your coated parts.

The Armoloy TDC® coating is fully compliant with AMS 2438, AMS 2460, and most customer-specific standards throughout the chrome coatings industry. Armoloy of Illinois operates processing tanks dedicated to AMS 2438 requirements and is capable of coating items to this standard up to 12 feet in length. Armoloy coatings can be applied to nearly all ferrous and non-ferrous base materials except for Aluminum and Titanium. Check with your Armoloy engineer for Aluminum coating options.

Armoloy of Illinois has years of experience meeting the rigorous demands of the industry’s most recognizable names. We work closely with each of our customers to establish requirements and custom-tailor solutions that best meet their needs. Armoloy of IL’s Quality control department employs extensive inspection and testing regimens, including 100% visual and deposit thickness verification, wear resistance, hardness, corrosion resistance, adhesion, and hydrogen embrittlement testing, and surface characteristic checks. Armoloy’s experienced staff will support all quality control and quality assurance initiatives required for your project, including FAI, PPAP, manufacturing and quality plans, controls plans, FMEA’s, gage R&R’s, and more.

Typical applications in the Aerospace industry include:

  • Valves
  • Bearings
  • Landing Gear
  • Rods/Shafts
  • Pistons
  • Transmission Components (gears, pinions, splines)
  • Safety Devices (latches, pivot pins)
  • Auxiliary systems

The Armoloy family of coatings are specifically designed to keep machinery and equipment running longer. For increased wear life, reduced friction, protection from corrosion and galling, and many other benefits, Armoloy of Illinois provides a full range of metallic surface coatings to the manufacturing community. High precision is our specialty.

Armoloy provides industry-leading protective metallic coatings that benefit various industries, including food processing/packaging, oil/gas extraction, Aerospace, medical, and nuclear industries, to name a few. Metal surface treatments tailored to these applications must withstand extremely harsh conditions and provide added durability capable of extending the life of components and systems. Our experienced staff can help engineer the right metal finishing solution to your application.

Our proprietary metal surface treatments are fully compliant with the industry's most rigorous requirements and certifications. At less than 170ᵒF, the Armoloy metal finish process is considered a "cold process" that will not distort or anneal coated parts. The Armoloy coatings form a hard protective metallic surface with an absolute bond to the base metal that will not affect part tolerances or balance. This thin, precision coating will improve surface hardness and lubricity while dramatically increasing your coated parts' wear life. Our stringent quality requirements and onsite product testing will ensure your parts meet strict industry standards.

Armoloy offers a variety of coating solutions engineered to solve your coating needs. The Armoloy TDC/XADC coating will not flake, chip or peel from your base material ensuring a safe coating process that is food and medical application safe. Your maintenance and machinery expenses will lessen thanks to the coating's increased wear resistance leading to decreased downtime and replacement costs. Don't settle for traditional metallic plating shortcomings when you can have the Armoloy family of coatings protecting your valuable automated systems and components.
