This kind of wear is the rubber on the rough friction surface, and has a large coefficient of friction, the resulting wear phenomenon. The abrasion process, on the wear surface of the rubber, there are these scratches parallel to the sliding direction, i.e., tiny cuts are produced on the rubber friction surface. When the protrusions move forward, the isometric parallel lines become curved, which proves that the surface layer is deformed and there is stress.

The front of the projection is in compression and the rear is in tension. When the rubber strength is less than the friction force, the rubber friction surface. A crack is created on the rubber friction surface, and a tear mark appears. The lower the hardness, the greater the pressure, the deeper the scratches.

In the rough friction surface, there are many such projections, friction, the rubber surface will appear on these perpendicular to the sliding direction of the convex stripe.

The rougher the contact surface, the smaller the hardness, the wider the abrasive stripe, the greater the abrasive strength. In the continuous friction process, the convex ridge is constantly being polished, and constantly repeated friction appears new convex ridge stripes, this process of repetition, so that the rubber abrasive wear.
