Armcoat Plating

ARMCOAT Plating is a proprietary chromium coating applied to metal to substantially increase wear and corrosion resistance. The Armcoat process will also provide excellent lubricity, adherence and uniformity, protecting it from the eroding effects of friction, chemicals and weather.

ARMCOAT Plating will not exceed .0002" total growth under normal circumstances. This will eliminate undersize design calculations in most applications.

ARMCOAT is compatible with most ferrous and non-ferrous metals, allowing maximum flexibility in choosing base materials. Cost savings may also be created by the elimination of costly base materials, such as stainless steel, and that the Armcoat process requires no additional grinding or secondary applications.


  • Hardness: Armcoat has a hardness in excess of 70 Rockwell "C". When measured by conventional micro-hardness methods, the base metal will modify the mearsurement to some degree. Vickers Diamond measurements produce a 1020-1100 hardness rating.

  • Corrosion Resistance: Armcoat will resist attack by most organic and inorganic compounds except sulfuric and hydrochloric acids. Armcoat will enhance all base metals, although porous and improperly prepared surface finishers can affect the corrosion-resistant properties of Armcoat.

  • Heat Resistance: Armcoat will withstand temperatures of -400 degrees F. At elevated temperatures about 1300 degress F, it will react with carbon monoxide, sulphur vapor and phosphorus. At bright red heat, oxidation occurs in steam or aliki hydroxide atmospheres. Hardness and wear resistance will reduce to some degree at temperatures above 700 degrees F.

  • Hydrogen Embrittlement: Armcoats pre-process surface preparation and the process itself, prevents the embrittlement phenomenon from occuring. The process will not necessarily remove pre-induced conditions.

  • Adhesion: Armcoat will not crack, peel, flake, chip or separate from the base metal under standard ASTM bend tests or under conditions of extreme heat or cold.

  • Effect on Base Metal: Armcoat will not significantly affect the yeild, tensile or fatigue properties of the base metal.

  • Coefficient of Friction: Measurements made at 72 degrees, no lubricants, using other materials for comparision.
