Bearing Surfaces

Wear

 

The removal of material, with the generation of wear particles under an applied load and in relative motion

 

Tribology is the study of wear and lubrication

 

Wear mechanisms

 

Adhesion

- bonding of the surfaces when pressed together

- may pull away material from the weaker surface

 

Abrasion

- asperities on the harder surface cut and plough
