The Armoloy Proces
Armoloy® is a low-temperature, multi-state process of electrocoating based upon chrome-plating technology. Instead of using conventional chrome-plating solutions and parameters, the Armoloy process utilises a proprietary chemical solution. The solution and application process are carefully monitored to produce a very thin, dense chromium coating. Armoloy deposits a crack-free satin matte finish of 99.9 percent chromium on the base metal surface, whereas most conventional chrome-plating process deposits will be in the 82 to 88 percent chromium range.
The Armoloy process involves a special pre-cleaning and removing of the matrix on the base metal's surface by special proprietary means followed by a modified electrocoating process that causes the chromium element of the Armoloy solution to permeate the surface porosity of the base metal. It is during this process that the absolute adhesive characteristics and qualities of the Armoloy are generated. The Armoloy coating actually becomes integrated with the metal itself. The result is a lasting bond and a continuous, smooth, hard surface. The surface will not chip, flake, crack, peel, or seperate from the basis metal on the standard ASTM bend tests or under conditions of extreme heat or cold.
Armoloy can be applied to all ferrous and nonferrous metals, but is not recommended for aluminium, titanium or magnesium. Armoloy makes it possible to use standard ferrous steels in place of stainless steel in many applications, including food processing and medical environments. |

Value-added benefits of ARMOLOY TDC Coating.
- 78Rc Surface Hardness
- Reducing wear and friction in moving parts
- Absolute adhesion to basis metal – no chipping, cracking, flaking or peeling
- Improved release characteristics in plastics forming tools–cores, cavities, lifters, pins, screws, plates
- Reduced maintenance and part replacement costs
Extraordinary Properties.
ARMOLOY TDC technology is unlike all other conventional hard chrome plating operations. Our proprietary TDC coating conforms precisely to details in metal tools, resulting in a hard (78Rc), slippery, and corrosion-resistant tool surface.
RMS finishes will improve slightly, to  (2 micrometers) . (Below (2 micrometers) the process may deter slightly.) Surfaces greater than  (1.6 micrometers) will reflect greatly improved finishes.
Both internal and external surfaces on all part configurations can be uniformly processed.
Employed as the finishing step for machine parts and manufactured components, Armoloy imparts a satiny, silver matte, micronodular finish.
ARMOLOY TDC Takes the Heat.
Withstands temperatures of -240°C to 850°C
(-400° to 1560°F).
- 78Rc Wear-Resistant Hardness.
- 78Rc Surface Hardness
- Vickers Diamond: 1360/1400

A Guideline for ARMOLOY TDC Success.
As the surface hardness and surface finish of your basis metals improve, the performance of the ARMOLOY TDC coating also improves.
To maximize ARMOLOY TDC performance, components should be engineered to a minimum of 50Rc, 40 pt. carbon steel with a minimum surface finish of  (0.8 micrometers).
ARMOLOY TDC can be applied to nitrided (QPQ) surfaces- all nitrided (QPQ) components submitted for ARMOLOY TDC coating should be clearly identified as having been nitrided (QPQ).
Prevention of Hydrogen Embrittlement.
ARMOLOY TDC process control prevents the embrittlement phenomenon from occurring, though original manufacturing conditions may not, necessarily, be removable.
The ARMOLOY TDC process will not affect the tensile, yield or fatigue properties of the basis metal. Pre- and post-baking are available upon request or specification. ARMOLOY TDC certifies to AMS-2438,AMS QQ-C-320,AMS- 2406, and most other military/industrial specifications
Corrosion Resistance.
ARMOLOY TDC resists attack by most organic and inorganic compounds, with the exception of sulphuric acid and hydrochloric acid.
Inferior metal surface finish and low part hardness may inhibit ARMOLOY TDC’s corrosion-resistant properties.
Tested in accordance with ASTM-B117 and AMS-2438.
Safety and Cleanliness.
FDA/USDA approved for use, without concern, on food processing equipment, in clean room environments and in medical/pharmaceutical applications. Independent testing has proven no issue of toxicity or skin irritation in ARMOLOY TDCcoated parts.
The ARMOLOY Shield: Five Points of Promise

- Person-to-person engineering consultation and a commitment to further education.
Low Coefficient of Friction
ARMOLOY TDC imparts a micronodular, low-friction surface finish. Reduced friction means reduced heat, prolonging the wear life of high-temperature tools.

Metal Preparation
Parts should be surface finished-prior to shipment to ARMOLOY for processing. Removal of excessive paint, scale, rust or corrosion by ARMOLOY may entail additional costs.
Because surface dimension is not significantly increased by coating,ARMOLOY TDC will not fill scratches, pits and dents but rather conform to them. Removal of normal oil or grease prior to coating is standard ARMOLOY procedure. |

Part Submission
Customers should submit parts to be processed accompanied by instructions indicating those surfaces requiring ARMOLOY TDC coating. Masking of individual details is available. Basis material and hardness of the part should be specified.
All parts to be shipped to ARMOLOY for processing should be properly packaged to prevent damage and corrosion. Containers adequate to obtain maximum protection during shipping should be used. |
