Low Friction Coatings

Think all low friction coatings are the same? You may be surprised. That's why staff and sponsors of Industrial Coatings World.com are here to help.

Your design is finished. And the engineering is sound.

Get ready to choose your low friction coating!

What is friction? We see it as the opposing force between two bodies or materials that dampens motion. There are two forms:

Static Friction-- forces acting upon a body at rest, set in motion. If the object doesn’t move when acted upon by a force, this is considered a static condition. Generally, the static force from the interlocking surfaces will increase and prevent relative motion up until some relative threshold where motion occurs.

Dynamic Friction-- forces slowing a body already in motion. If the force is sufficient to move the object, this is considered a ‘dynamic’ or kinetic condition.

Do you know the contributing factors of your own friction? Here are some examples.

Frictional motion includes: sliding or rolling, even fluid. Mostly, it is the result of surface roughness, molecular adherence, or deformation effects.

Calculating the coefficient of friction seems simple enough (ratio of tangential and normal loads). Yet, contrary, it is a complex, system-dependent parameter.

Maybe your friction is not easily quantified. And you are just looking for qualitative improvement. What’s the best coating for low friction?

Don't ignore your environment. Load, speed, distance, temperature, hardness, surface finish and counter-face all play a role. So be sure to ask about your coating's flex or shear strength in relation to either parent material surface and applied force.

The harder the base material (resistance to plastic deformation) the more effective the lubrication.

Which surface should you coat? Generally, coating the softer of the two surfaces will extend the life of the ‘system.’ Friction will be slightly higher if both surfaces are coated than if only one surface is coated. However, wear life will increase if both surfaces are coated. You will have to determine which is more important: longer wear life or lower friction.
