What is Industrial Hard Carbon, the Product?

A Diamond-Like Coating with Unlimited Custom Applications.

Characterized by its extreme hardness, high lubricity, high wear-resistance, and high corrosion resistance, Industrial Hard Carbon thin film is applied to parts by a proprietary plasma-assisted chemical vapor deposition process.

IHC films are created from layers of nano-crystalline diamond and nano-crystalline silicon carbide in an amorphous matrix of both elements. It is the unique combination of these elements that give Industrial Hard Carbon its wide range of properties and extremes in those properties, and its qualities can only be surpassed by pure diamond. And while IHC thin film is a one step development process, majority of the time the product requires several, often simple, changes throughout its lifetime.

Because of its unique characteristics separating it from other thin films, Industrial Hard Carbon diamond-like coating succeeds where other coatings fail.

IHC's properties

Extreme Hardness

Less than or equal to 17 GPa, or less than or equal to 85 Rc.

High Lubricity

Significant reduction in coefficient of friction lab tests and required torque in field applications compared to bare metal; 50 percent or greater friction reduction with no lubrication as compared to bare metal is typical.

Wear Rate

Significant reduction in wear resistance.

Flexural Strength

Can withstand less than 46,000 psi tensile and compressive stresses, and compressive strain of 0.17 percent.

Corrosion Resistance

Protects underlying substrate from most corrosive agents.

Conformal to Substrates

Plasma assisted CVD, by definition, depositions evenly over all surfaces of a part without special fixturing or rotation.

Operating Temperature

Operates from -200°C or -320°F to less than 600°C or 1112°F, dependent on oxygen partial pressure.

Thermal Conductivity

Less than 10 W/cm°K.

Electrical Resistivity

Less than 109 ohm cm, doping options to lower r.

Why Industrial Hard Carbon, the Company?

Where Other Diamond-Like Coatings Fail, IHC Succeeds.

Industrial Hard Carbon, LLC is much more than just a thin film coating company where companies can send products to receive diamond-like coating. IHC consults the client on their options and customizes the application to each client’s specific needs. And because of IHC’s own manufacturing efficiency, reactor and tooling design expertise, thin film coating can be applied to just one item or thousands for a reasonable charge.

Surface prep treatment is completed in-house to prepare the part for the adhesion of the coating, and this ensures the diamond-like coating is applied evenly to all areas. In fact, Industrial Hard Carbon is so certain of the quality of its thin film that clients are suggested to test IHC’s diamond-like coating compared to competitors. 

And due to IHC’s process and equipment, turnaround time is typically less than two weeks, but items can be rushed to be turned around in as little as 24 hours if needed.
