Abrasion Resistant Coatings
Abrasion is one of the main causes of component failure in almost every industry. By definition, abrasion is a wearing, grinding, or rubbing away by friction. Abrasion resistant coatings are a viable option to extend a part’s life cycle or to improve part performance.
Abrasion and wear resistant coatings can:
Extend component life
Improve part performance
Decrease costs
Associated with part servicing and replacement
Increase chemical resistance
Allowing for functionality in harsh conditions
PTFE Based Abrasion Resistant Coatings
An abrasion and wear resistant coating functions by reducing the friction caused by one component rubbing against another. PTFE (or Polytetrafluoroethylene) provides a low coefficient of friction that prevents the scoring, galling, or sticking of mating components.
Abrasion resistant coatings can be solely PTFE in chemistry or contain other additives to reinforce their resistance to wear or increase their lubricity. Graphite and molybdenum disulfide are inorganic solid based lubricants and can be used as a standalone coating or in conjunction with PTFE. These lubricants are ideal for applications where a component actuates inside another as the coating can transfer from the coated to the un-coated component, creating two lubricating surfaces.
Whitford, Henkel, and Dow make a variety of very successful abrasion and wear resistant coatings that DECC utilizes.
