Low Friction Coatings

low friction coatings

Low friction coatings normally include a low friction polymer, typically a fluoropolymer like PTFE (commonly referred to as TEFLON). Low friction coatings can be simply the polymer itself, usually sprayed and baked on to the part, often with a primer to provide effective adhesion. The low friction polymer may be reinforced with a hard filler to provide increased wear resistance.

Other low friction coatings can be produced by adding the low friction polymer to another, harder, coating, such as electroless nickel or a thermal spray ceramic.

To understand the principles of friction more fully, we recommend you read our tutorial on wear and wear resistant coatings.

Poeton offer a wide range of low friction coatings. (Please follow the links to the product pages for detailed data on applications and friction values.)

Polymer Composites Under the Apticote 200 series, there are six different low friction coatings. Their properties are individually tailored so that some are wear resistant (but with slightly higher friction) and others are softer, more suitable as non-stick coatings. We recommend you read our Designers Guide on Apticote 200 for much more detailed information.

Electroless Nickel/PTFE. This is probably the best example of a low friction coating on the market. Poeton have tailored their Apticote 450 coating to produce the lowest friction combined with the highest wear resistance. See also Poeton Apticote 460 a more advanced Electroless Nickel composite that acts as a low friction coating as well as providing superb corrosion resistance.

Hard Anodising Composite Coatings. Applicable only to aluminium alloys, hard anodising composites produce a hard oxide wear resistant coating infused with a self lubricating polymer (Apticote 350), transformed from the parent metal rather than deposited as a separate coating. It is an excellent low friction coating, most suited for lighter loads. See also Poeton Apticote 355 a more advanced composite that acts as a low friction coating as well as providing superb corrosion resistance.

Thermal Spray Composites Thermal spray ceramics, with a tailored structure, can be infused with self lubricating polymers to provide extremely durable low friction coatings.
