Thin Dense Chromium is a low-temperature (58°C to 60°C), surface coating process based on chrome-plating technology, but displays higher hardness, along with better lubricity and corrosion than any other chromium coating on the market. Through a proprietary chemical solution, Armoloy is produced as a hard, thin, dense chrome coating, where its micro-nodular surface texture boasts benefits that other coatings can’t produce, enhancing use, and reducing wear.
Properties of Armoloy:
· High hardness – At 78HRc, Armoloy Thin Dense Chrome is one of the hardest coatings available.
· Nodularity – A key property of Armoloy is a nodular effect which increases lubricant retention and reduces surface contact area. This in turn improves the wear life and reduces friction.
· The dense nature of the coating means good corrosion resistance as the coating is almost free of micro-cracks (conventional chrome +/- 40 micro-cracks per cm2).
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.
· Uniform deposits with almost no edge build-up. Suitable for threads and sharp edges.
· No requirement for post finishing (except special applications)
· Matt silver satin chrome finish
· Thermal Stability of between -240˚C and 450°C
· Can be applied locally where required
Typical Thickness:The standard deposit thickness of Armoloy TDC ranges between 0.0025 -0.0075mm (2,5 – 7,5 microns)

No chipping, cracking or peeling from the basis metal therefore absolute adhesion to the base metal
Reduces fretting and pickup or galling
Reduced wear and friction of moving parts
Enhanced corrosion resistance.
Improved release characteristics on moulds and dies
Reduced maintenance and machinery replacement costs
Smoother, faster and quieter running equipment
Complies to AMS-2438a (10/98)
Can be applied to internal and external geometries
Protects expensive replacement parts such as stainless steel and tool steels

Armoloy can be applied to nitrided surfaces, but all components must be clearly defined as being nitrided before coating. Armoloy will not affect the tensile, yield or fatigue properties of the basis metal.
