When to use Dicronite®

Competitive drivers, design engineers, automotive mold technicians and manufacturers use Dicronite® to reduce friction when:

  • the power output of an engine is being robbed by friction losses

  • sliding wear is limiting component lifetime

  • excess friction is resulting in temperatures that are too high

  • threaded components are galling and/or seizing

  • maintenance is too frequent and causes costly downtime

  • experiencing less than desired engine performance

  • excessive noise in moving parts is present

Where to use Dicronite®

Common automotive applications that use Dicronite® include but are not limited to:

  • gears

  • valves

  • camshafts and crankshafts

  • bearings

  • drivetrain components

  • threads

  • pins

  • bushings

  • pistons

  • rods

  • gearboxes 

  • anti-lock breaks

  • automotive plastic molding

FAQ

Most frequent questions and answers

For components that are already lubricated by oil or grease, we recommend using Dicronite® along with the existing lubrication. This helps optimize performance and ensure maximum output.

Yes. Generally, for holes or inside diameters, there is a depth limitation of two times the diameter. However, for larger diameters it may be possible to apply to a greater depth.

The Dicronite® coating may wear over time, but the wear rate will be specific to your application. We recommend testing Dicronite® in your application to ensure the wear life is sufficient.

A previously coated part can be re-processed to produce a new Dicronite® coating.

Ensuring parts are sent in without excessive amounts of dirt, grease, grime, or residues will help you avoid additional costs for extra cleaning. However, all parts are degreased prior to coating so parts don’t have to be clean when sent in.

Sliding Wear

Sliding wear occurs when two surfaces slide against one another causing material loss to one or both surfaces. Over time, this can result in component failures, additional maintenance, and costly down time.  

Coating components with Dicronite® can help minimize this wear and reduce the need for maintenance and down time.

Tight Tolerance Lubrication

Extremely tight tolerances can present challenges when lubricants or coatings are needed to reduce friction. Many products are available to help reduce friction, but in the case of very tight tolerances, few can be integrated without the need for adjustments.

Dicronite® has an average thickness of 0.5 microns (0.00002 inch) or less. This precision thin film allows users to incorporate Dicronite® on designs with tight tolerances without the need for design or manufacturing changes.

Vacuum Environment Lubrication

Vacuum environments present a challenge for lubrication. Many conventional lubricants aren’t effective under vacuum and are largely vaporized.

Dicronite® can be used in vacuum to reduce friction where other lubricants can’t function. The outgassing of Dicronite® under vacuum conditions is well below screening levels for spacecraft materials per ASTM E595.

Energy Lost to Friction

Friction is wasted energy! Systems with critical mechanical power output need to be extremely efficient.

Dicronite® optimizes mechanical efficiency by reducing friction losses and can even work in tandem with existing lubrication to further optimize efficiency.

Dicronite® is especially useful in precision systems, extreme environments, or where minimizing size and weight is vital.

Fretting

Fretting is a unique form of sliding wear that occurs when contact surfaces oscillate over a very small range of motion. Although it may seem minor, this surface wear can ultimately lead to fatigue cracking and devastating damage.

Dicronite® helps remedy fretting by providing lubrication at contact surfaces. This effectively reduces the wear and surface stresses that cause so much damage.

Dicronite® can be integrated into existing designs and assemblies without any other adjustments for seamless reduction of fretting wear.

Extreme Temperature Lubrication

Extreme low or high temperatures can be challenging environments for lubrication. At low temperatures, conventional lubricants may be too viscous to be effective, while extreme high temperatures can result in breakdown of the lubricant.

Dicronite can be used in extreme environments to ensure effective lubrication while also being used in combination with oils and greases.

Dicronite is stable across a wide temperature range:

  • up to approximately 538°C (1000°F) in air
  • up to approximately 1316°C (2400°F) in vacuum
  • down to approximately -188°C (-305°F)

Excessive Heat from Friction

As friction in an assembly generates heat, elevated temperatures can result in unwanted operating conditions.

This can cause overheating and accelerate the breakdown of materials, resulting in costly maintenance and down time or destructive failure.

Proper lubrication can help minimize friction, reduce heat, and increase mechanical efficiency. Coat parts with Dicronite® to avoid excessive maintenance and ensure components will run as efficiently as possible.
