You may have seen the word on a roll of tape or on the packaging of a post-it pad: adhesive. These examples make it easier to understand what adhesive wear is. Adhesive wear is when two parts move against each other. The surface heats up due to the movement and excessive surface pressure. This makes the two parts stick together and it is pulled apart again by the movement. This causes damage, or wear, to the surface. Another name for this is 'cold welding'. The particles that are released during the peeling as an intermediate substance and in turn cause abrasive wear. In practice, this form of wear occurs, among other things, in machine parts that are insufficiently lubricated.
