What is Armoloy ARMOLOY is a Thin Dense Coating applied through an electro coating process under license from the ARMOLOY Corporation USA. It is an extremely hard precision coating applied to metal under rigid quality controls to produce amazing wear and corrosion-resistant surfaces. The coating can be applied to most metal types, ferrous and non ferrous, with exception to Magnesium and Titanium. ARMOLOY offers a unique solution to chromium coatings. Unlike conventional hard chrome, Armoloy is far more durable, flexible and can be applied to a far greater range of products and applications not possible through normal conventional means. Value-added benefits of ARMOLOY: • Deposit Thickness • Extremely Hard 78 HRc • Conformity • Reduced wear and friction of moving parts • Low heat application won't distort components • Higher resistance to corrosion than standard chrome plating • Performs in temperatures from -240°C to +840°C • Prevention of Hydrogen Embrittlement • No chipping, cracking or peeling from the base metal • Improved release characteristics on moulds and dies • Reduced maintenance and machinery replacement costs • Smoother, faster and quieter running equipment DEPOSIT THICKNESS ARMOLOY is deposited as a thin microscopic coating ranging from 2 to 7 micrometers in depth SURFACE HARDNESS When applied to a hardened substrate, the thin layer of ARMOLOY has a deposited equivalent hardness of 78 on the Rockwell C scale CONFORMITY ARMOLOY has excellent conformity, reproducing the original surface condition after coating, and can be applied to internal bores, blind holes, and complex shapes while maintaining good conformity. COEFFICIENT OF FRICTION Lubricity: With the exceptional hardness and the accuracy of the surface finish, ARMOLOY produces a super hard, 78 Rc microscopic nodular surface that reduces surface contact area, thereby decreasing the coefficient of friction and enhancing the benefits of lubricants. Armoloy provides a coefficient of friction 40% lower than lubricated steel (0.12 vs., steel at 0.20) resulting in a marked reduction in abrasion, erosion, adhesive wear, scuffing or galling, scoring and seizing.  PROCESS TEMPERATURE ARMOLOY process is performed at low temperatures (below 60° C), eliminating growth, distortion or warping. This low temperature process will not affect the mechanical characteristics of the base metal such as hardness, strength, creep, ductility, elasticity or toughness. CORROSION RESISTANCE ARMOLOY provides an excellent corrosion resistant surface. It is impervious to most organic or inorganic substances. Results obtained from the standard ASTM Salt Test have verified its effectiveness. ARMOLOY will not provide corrosion resistance to hydrochloric acid in any concentration; however, it has performed well when only vapors are present as in moulding PVC plastics. The surface inconsistencies experienced in standard plating does not occur with the thin dense chromium composition and microscopic thickness of the ARMOLOY coating. This attribute offers significant cost savings by allowing the substitution of low cost base metals for expensive corrosion resistant steels. HEAT RESISTANCE ARMOLOY will perform well at temperatures normally experienced in manufacturing. It will withstand ambient temperatures between -240°C to +840°C. Armoloy maintains its corrosion protection and friction reduction capabilities across this temperature range. PREVENTION OF HYDROGEN EMBRITTLEMENT ARMOLOY process control prevents the embrittlement phenomenon from occurring, though original manufacturing conditions may not, necessarily, be removable. The ARMOLOY 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 certifies to AMS-2438, AMS QQ-C-320, AMS-2406, and most other military / industrial specifications. ADHESION ARMOLOY will not chip, flake, crack, peel or separate from the base material under standard ASTM bend tests or under conditions of extreme heat or cold. ARMOLOY, being compatible with both ferrous and non-ferrous metals, allows maximum design selection of base materials. Magnesium and titanium are not considered good candidates for base material selection. IMPROVED RELEASE CHARACTERISTICS ARMOLOY helps reduce maintenance requirements and downtime in the mould industry due to the smooth, micro-nodular surface produced by the coating. This will lead to more shots and shorter cycle times. Moulding areas stay cleaner longer and require less maintenance while burnt on plastic and rubber can be quickly removed. |
