Armoloy® Nodular Thin Dense Chromium is a low-temperature (136°F to 140°F), multi-stage metal finishing process based from chrome-plating technology.

Unlike conventional chrome-plating processes, Armoloy® utilizes proprietary chemical solutions and unique application techniques that are carefully monitored to produce its Nodular Thin Dense Chromium coating which follows the exact contours of the basis metal with accurate deposit thickness.

Armoloy® can be applied on a variety of shapes, sizes, forms and surfaces, creating a hard, slippery, and corrosion resistant surface. All threads, flutes, even scratches and blemishes, are reproduced in detail with 100% adhesion to the basis metal.

Consumer tests conclusively prove that surfaces treated with Armoloy® Nodular Thin Dense Chromium deposits of 0.0001" to 0.0002" per side are harder and have superior anti-friction, anti-corrosion, and increased lubricity properties than conventional chrome plated surfaces.

SPECIAL ARMOLOY®  PROPERTIES

	NODULARITY - What most sets Armoloy® coating apart from conventional chromium coatings is its micro nodularity, seen here at approximately 500X magnification.  These nodules reduce contact surface and retain lubricants, in effect acting like "micro ball bearings" that dramatically reduce friction, while exhibiting improved wear life and corrosion resistance.
	Armoloy® achieves nodularity using a refined electrocoating process that deposits a 99% pure metallic chromium layer of typically only .0001" - .0002" thickness that bonds with the base metal surface and provides absolute adhesion without changing base metal characteristics.

ABSOLUTE ADHESION – Armoloy® coating will not chip, flake, crack, peel or separate from the base metal under standard ASTM bend tests or under conditions of extreme heat or cold.

HEAT AND COLD TOLERANCE – Armoloy® coating exhibits outstanding temperature tolerance and stability, withstanding temperatures of –400°F to 1600°F (-240°C to 870°C). At elevated temperatures above 1200°F it will react with carbon monoxide, sulfur vapor, and phosphorous. A bright red heat oxidation occurs in steam or alkali hydroxide atmospheres. At temperatures above 1400°F, hardness and wear resistance will be reduced.

HARDNESS – Armoloy® Nodular Thin Dense Chrome has an equivalent hardness of 78 Rc as deposited. Vickers Diamond measurements produce a 1020-1100 hardness rating. The 78 Rc surface hardness shows no brittleness nor micro-cracks in its surface when viewed up to 500X.

UNIFORM DEPOSITS WITHOUT THICKNESS OR EDGE "BUILD-UP" – Armoloy® coating will range from 0.000050" to 0.0004" (1 micron to 10 microns) per side. Normal proven average deposits are in the 0.0001" to 0.0002" per side range (2,5 to 5 microns). The Armoloy® process does not create "edge build-up".

Armoloy® thickness is always in direct relation to the base metal and will vary from one base metal to another. However, thickness established for each will remain constant and predictable. Internal and external surfaces on nearly all shapes and configurations can be uniformly processed.

CORROSION RESISTANCE – It resists attack by most organic and inorganic compounds with the exception of sulfuric and hydrochloric acids. Conforms to ASTM-B117 and other corrosion specifications. Armoloy® coating will meet or exceed 440C stainless steel in corrosion resistance in many applications. Of course, base metal porosity and imperfections as well as surface hardness will affect basic corrosion-resistance properties.

NO HYDROGEN EMBRITTLEMENT -- Armoloy® processing and pre-process surface preparation prevents the embrittlement phenomenon from occurring. Pre-induced conditions may not necessarily be removed. Armoloy® coating will not significantly affect the tensile, yield or fatigue properties of the basis metal.

SAFETY -- Armoloy® is USDA/FDA compliant for use on food processing equipment and in pharmaceutical applications.

AESTHETICS -- Used as the final coating on parts and equipment, Armoloy® coating imparts an attractive satiny silver matte or nodular finish.
