XADC-ARMOLOY® Improving the Technology of Diamond Chrome Coatings 98Rc XADC-Armoloy®: The Best of Two Worlds Using advanced "Ultradiamond" technology developed by Soviet Union, Military Research Specialists for military and aerospace applications, The Armoloy Corporation has created a new, harder metal coating called XADC-Armoloy. This new coating eclipses the normal life expectancy of metal surfaces subjected to extreme wear, abrasion and corrosive stress. XADC-Armoloy coating, incorporates perfectly spherical and extremely dense "Ultradiamond" composite particulate into the Armoloy Process in an evenly dispersed form, to achieve hardness measurements exceeding 98Rc. XADC-Armoloy offers enhanced durability, lubricity, adhesion, and resistance to abrasion surpassing all other known coatings. These enhancements provide added durability, lubricity and resistance to abrasion that surpasses all other known coatings to date. XADC-Armoloy exceeds the boundaries of standard coatings available in today's marketplace without the need for special engineering design or production modifications. A precision coating deposit of .0001/.0003" (0,0025 - 0,0075 microns) is carefully bonded to the basis substrate, providing a thin, hard, protective coating with no effects of brittleness in its applied form. Applied at temperatures under 200°F (100°C) there are absolutely NO changes in the basis metals that the XADC-Armoloy coating is applied to. Like Armoloy TDC, XADC-Armoloy will adhere and perform well on all major ferrous and nonferrous basis materials with the exception of aluminum, magnesium and titanium. The above photo shows the absolute bond between XADC-Armoloy and the base metal. Red represents the Armoloy Coating. Yellow shows the absolute bond that is formed during the XADC-Armoloy Process, while black represents the base metal. XADC-Armoloy will not fracture from the basis metal unless the metal substrate itself fractures or fatigues. The absolute, positive adhesion that is created with the special application of XADC-Armoloy is a major benefit to its users. XADC-Armoloy meets standard ASTM B 489-85 bend test without chipping, cracking or separation from basis material. Comparative Hardness XADC-Armoloy withstands temperatures from -400°F to 1600°F (-240°C to 870°C). At temperatures above 1200°F, XADC-Armoloy will react with certain materials such as carbon monoxide, sulfur vapor and phosphorus. Temperatures above 1800°F are not recommended. Friction Reduction: The XADC-Armoloy process provides a unique nodular texture which creates a ball-bearing like surface. This point-to-point surface contact lends itself to reduced friction, increased lubricant retention and lower operating temperatures. XADC-Armoloy coated parts operate faster, smoother, and at cooler temperatures than uncoated parts, which reduces friction to greater degrees than other coatings in today's marketplace. Galling conditions are eliminated with XADC-Armoloy, which effectively allows XADC-Armoloy coated parts to operate against other XADC-Armoloy coated parts. Testing indicates the inherent lubricity of XADC-Armoloy may reduce the need for lubrication, providing cleaner working areas and more environmentally friendly processes. Corrosion Resistance: Tests have shown that XADC-Armoloy provides corrosive resistance exceeding 440C stainless steel. Corrosion tests utilizing ASTM B117 procedures have met and exceeded the requirements found in ASTM-2438. The XADC-Armoloy coating enhances the durability of components used in a wide range of applications from plastic injection mold tooling to aerospace applications that require long life expectancy, extreme wear protection, low frictional characteristics and corrosion protection. 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. 2001 Western Michigan University Erosive Wear Results of Coatings and Copper Alloys ALLOY SURFACE TREATMENT CYCLES C18000 XADC - Armoloy 635,000 C18000 Armoloy TDC 155,000 C18000 TiN 57,000 C18000 Std.
