Thin, dense, chromium coatings with hardnesses of 78/98 Rc
Armoloy TDC is a hard, thin, dense chrome coating with a micro-nodular surface texture that was developed to protect a wide range of tools and components. The Armoloy TDC (thin dense chrome) coating is applied in a chemical bath by means of a proprietary process. Armoloy TDC has a hardness of 78 Rc; XADC-Armoloy features the inclusion of synthetic nano-diamond to the TDC bath, resulting in hardness of 98 Rc.
Armoloy® TDC Thin Dense Chrome
When first introduced in 1957, the Armoloy TDC provided a 70 Rc as-applied coating. During 2000, the company embarked on a series of experiments to improve this property, with results where hardness has now reached 78 Rc. The same excellent adhesion, high ductility, and excellent corrosion resistance of the Armoloy TDC has not been compromised with the improved hardness level.
To develop the greater hardness, density has been increased. In fact, the density of Armoloy TDC is such that no micro-cracks are visible in the coating surface, even at 500X magnification. Therefore, when properly engineered on metal components, the Armoloy TDC coating provides exceptional resistance to wear, corrosion and greatly reduced friction.
The coating also features a microscopic pattern of nodularity. This is significant in that the nodularity reduces the area of coated surface exposed to parts in contact with it, thereby substantially reducing the wear and friction rate. Furthermore, our micro-nodularity retains lubricants longer, further reducing friction. In other words, reduced surface area + high hardness = longer wear rate = longer wear life.
Another important aspect of Armoloy TDC is the uniformity of the deposit thickness of the coatings, which are applied at thicknesses of 1 to 17,5 microns (0.000040 to 0.0007 in.). This is a beneficial factor in that thinner coatings can be applied with a higher degree of uniformity to a tightly toleranced component. The recommended deposit thickness range of 2,5 to 7,5 microns (0.0001 to 0.0003 in.) are uniform to within +/- 0,625 microns (0.000025 in.). This allows Armoloy TDC to return a finished product to its customer, eliminating the need for any post-coating operations.
Our TDC coatings have been applied to bearings, tools and dies, pumps, plastic and rubber mold tooling, nuclear and aerospace parts, hydraulics, food processing equipment, and a wide variety of components where wear, abrasion, high friction and corrosion environments are prevalent.
XADC-Armoloy® - Adding Nano-diamonds to Armoloy TDC - 98 Rc
In 1997, after three years of research and development, Armoloy introduced XADC, its newest coating which attains a surface hardness of 98 Rc through the addition of synthetic nano-diamond particulates to the TDC bath. In addition to its 98 Rc hardness, its coefficient of friction is 20% lower than that of other TDC coatings.
Western Michigan University Study
A recent study by Dr. Paul Engelmann and others at Western Michigan University demonstrated XADC's outstanding performance. The XADC-Armoloy coating out-performed standard hard chrome plating, electroless nickel, and titanium nitride in an injection molding application on copper-base metal tooling molding a 33% glass-filled nylon, a highly abrasive plastic resin. As the table shows, XADC coated C18000 copper survived for 635,000 cycles. Armoloy TDC coated copper persisted for 155,000 cycles, and titanium nitride tolerated only 57,000 cycles.

1957: Harry L. Nickelson of Fort Worth, Texas developes a thin dense chromium process for metals and names it "Armoloy" (The "Armor Alloy"). Initial applications include cutting tools and small wear parts.
1962: Nickelson decides to license his proprietary process and creates the Armoloy Company to serve as the licensing agent. The first license is issued to two engineers in western Pennsylvania.
1963 -1968: Additional licenses are issued and three new Armoloy plants open in the United States.
1969: Jerome F. Bejbl obtains a license from Nickelson and opens Armoloy of Illinois in DeKalb, Illinois.
1972: Improved Armoloy product development results in national award recognizing outstanding performance in the coating industry.
1978: Bejbl purchases the Armoloy Company from Nickelson and moves the company headquarters from Fort Worth, Texas to DeKalb, Illinois. The company is renamed The Armoloy Corporation.
1985: The first international franchise is established in England and continues to operate today as Armoloy (U.K.), Limited.
1988: ATC Armoloy Technology Coatings begins operation in Mosbach, Germany.
1995: Armoloy establishes a new U.S. franchise in Sumter, South Carolina.
1997: Armoloy Corporation introduces XADC - Armoloy® to the market. Current XADC - Armoloy® licensees are Armoloy of Illinois, Armoloy of Connecticut, and Armoloy of Western Pennsylvania.
2002: Armoloy enhances coating hardness of Armoloy TDC® to 78Rc and XADC-Armoloy® to 98Rc.
Since 1957, our company has grown from one plant with revenues of $50,000 to 11 plants with worldwide revenues of $16 million in 2001.
Today, Armoloy® covers the United States with eight franchises and three in Europe.
Current plans include expansion into the western United States, eastern Europe, the Pacific Rim, India and Japan.
Armoloy Corporation includes two additional licenses in other processes for metal treatment: The Electrolizing® Process in Rhode Island and France and ME-92 Medical Coating in Rhode Island.
