Abrasion & Wear Resistance

What is abrasion and wear?

Abrasion is the process of rubbing away the surface of something; wear means to become thin and disappear after repeated use or rubbing. The abrasion and wear of metal occurs through friction, as the contact between two metal parts creates asperities and fragmentation. As each part continues to move, the surface of the metal is ripped away. Abrasion resistance and wear are the main cause of component failure in almost every industry, increasing maintenance costs and reducing machine effectiveness.

Prevent abrasion and wear with coatings

An abrasion resistant coating will provide a thin layer of lubrication to protect metal parts from making physical contact with each other, protecting them from damage caused by wear and abrasion. The selection of the best lubricant, such as PTFE, moly, or graphite, for these applications depends primarily on the PV (Pressure X Velocity), atmosphere and operating temperature of the application.

Often, a Xylan coating provides enough lubrication to eliminate excessive wear. In most cases, friction and wear of the parts are reduced when one or both are coated with a dry-film lubricant. Also, the coatings serve as a thin cushion, spreading high point loads in bearing and reducing element fatigue. Coatings with abrasion and wear resistant properties have many advantages:

  • Extended part life of components
  • Decreased maintenance of components reducing cost and increasing uptime/productivity
  • Increased high-temperature resistance
  • Increased performance capabilities under harsh environmental conditions
  • Low coefficient of friction; preventing the scoring, galling or sticking of mating components
