Diamond Chromium Coating – Advanced Technology

In 1996, the coating 98Rc XADC coating was introduced. It offers today’s industrial design and engineering community the opportunity to expand their options to enhance the performance of their equipment and tooling. The coating helped in many ways. Some of the benefits to the coating are it helps to increase lubricity and better corrosion protection for food process die segments. It also helps with stamping applications, because the stamping applications show sharper cuts, no burrs and smoother finishes.

The also was an to the thin dense chromium coating to help with the corrosion. It was the addition of nano-diamond spheres to the thin dense chromium coating technology is unique, but still allows for cost effectiveness and rapid delivery to ensure in-budget and on-time delivery.

The XADC coating enhances the durability of components used in wide range of applications from plastic injection mold tooling to coating aerospace applications that require long life expectancy, extreme wear protection, low frictional characteristics and corrosion protection.

The coating has absolute adhesion. With the special coating it 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 the coating is a major benefit to its users. It compiles to the standard ASTM B 489-85 bend test without chipping, cracking or separating from the basis metal.

With the coating, the metal can be heated to temperatures under 200 degrees F (100 C). Even at this high temperature there are absolutely NO changes in the basis metals that the coating is applied to. Like Thin dense chromium coating, XADC will adhere and perform well on all major ferrous and nonferrous basis metals. Aluminum. Magnesium and titanium are not considered good substrates for the coating processes.

The coating is able to withstand temperatures from -400º F to 1400º F (-240º C to 775º C). At temperatures above 1200º F it will react with materials such as carbon monoxide, sulfur vapor and phosphorus. But certain temperatures above 1800º Fare are not a good idea.

It also helps to reduce friction with a greater degree than other coatings that are around today. Testing indicates the inherent lubricity of the coating may reduce the need for lubrication, providing a cleaner and more environmentally friendly workplace. Galling conditions may be eliminated with the help of the coating, which effectively allows the coated parts to operate against other coated parts.

It also helps with corrosion resistance. The tests have shown that coating provides corrosion resistance exceeding 440C stainless steel. The corrosion tests utilizing ASTM B117 procedures have met and exceeded the requirements found in AMS-2438. Basis material coated with the coating exceeds performance levels of uncoated materials multiple times. diamond burrs with metallic
