Abrasive Wear & Adhesive wear

Author:QINSUN Released in:2019-10 Click:1201

Mar abrasion is when a surface becomes permanently deformed, but the surface does not break.The terms abrasion and wear are frequently used interchangeably, however there is a difference. Abrasion is the action causing wear and ASTM defines it as “the wearing away of any part of a material by rubbing against another surface". Removal of a portion of the surface by some kind of mechanical action such as sliding back and forth of an object, rubbing, wearing tires on traffic paint, wind erosion and the like is termed wear abrasion.


It is the type of relative motion that is used to define the generated wear. The complexity of wear means that a number of modes can be recognized.

The main modes are outlined below:

Abrasive Wear - Wear because of hard protuberances or hard particles forced against and moving along a solid surface is known as abrasive wear. These hard particles may be common abrasives such as silicon carbide and aluminum oxide, or naturally occurring contaminates such as dust particles and sand [crystalline silica (quartz)]. Rolling abrasion or three-body abrasion occurs in case the abrasive particles are allowed to roll.
Adhesive wear – Adhesive wear is caused by localized bonding between contacting solid surfaces resulting in material transfer between the two surfaces or loss from either surface. Adhesive wear is not as common as abrasive wear and takes place when materials slide against each other without any lubrication. This type involves local cold welds being formed between surfaces contacting under a load and plowing or tangential shearing of junctions.
