Two Types of Anti-Corrosion Coatings

In the anti-corrosion industry there are a multitude of coatings that can be applied to machinery/ equipment to ensure its longevity is preserved. Although there may be particular coatings that are more applicable to individual industries, there are two types of anti-corrosion coatings that are universally the best to apply to equipment.

* Diamond Chromium Coating

* Thin Dense Chromium Coating

Applying either the diamond chromium coating or the thin dense coating to machinery in a variety of industries helps to protect individual pieces of equipment from rust, corrosion, pitting and overall damage that comes from constant use.

The diamond coating is for industrial use and allows for enhanced performance of equipment and tooling in a variety of industries. Nano-diamond spheres are introduced into the diamond chromium coating which makes this type of anti-corrosion coating unique to others that are used. This coating is very cost effective for many budgets and schedules. This coating boasts the comfort of absolute adhesion. It will not fracture and separate from the metal unless the metal itself is fractured or previously damaged. The diamond coating is generally applied at temperatures upwards of 200 degrees Fahrenheit and is compatible with many ferrous and nonferrous metals. Metals such as aluminum, magnesium and titanium are generally not suitable candidates for the diamond chromium coating.

The thin dense chromium coating is a on the opposite temperature spectrum as is counterpart, the diamond chromium coating. The thin dense chromium coating is a low-temperature product that is capable of being applied to many surfaces. Benefits associated with use of the thin dense chromium coating are: a strong surface hardness; reduced wear and corrosion resistance; adhesion to metals without chipping, cracking, flaking or peeling; improved performance in tool forming equipment such as cores, cavities, lifters, pins, screws and plates; and reduced maintenance to equipment and replacement equipment costs. The coating is able to significantly cut down on equipment maintenance by properly protecting the metal exterior from the start of use. Companies, both large and small, are very receptive to the potential for the thin dense coating to significantly cut down on equipment replacement costs. Large and specialized pieces of equipment can be quite costly to replace, and with the use of this coating that prospect is greatly reduced.

These two types of anti-corrosion coatings are popular among the following industries: rubber and plastics, nuclear, automotive, food processing, OEM machine tooling and bearings. Although other coatings are available on the market, these coatings offer the flexibility of varying temperature ranges and metal applications.
