Deformation Wear

Deformation wear occurs when two surfaces come into contact and undergo plastic deformation, resulting in material loss or surface damage.  It is a common form of wear in engineering applications where surfaces experience high contact pressures and relative motion.

When two surfaces are subjected to a compressive force, such as in sliding or rolling contact, the material undergoes plastic deformation rather than elastic deformation.  Plastic deformation occurs when the stress applied exceeds the yield strength of the material, causing permanent changes in shape or size.  This deformation can lead to material removal, surface roughening, or formation of wear particles.

Overall, understanding the mechanisms and factors contributing to deformation wear is crucial in designing components and selecting appropriate materials and lubrication strategies to enhance the durability and performance of mechanical systems.
