Rubber wear books

When a polymer sphere moves across a clean and smooth hard solid surface, the majority of the friction it experiences comes from the adhesion between the two surfaces. This adhesive force plays a significant role in determining the resistance encountered during motion. Additionally, the friction involved in such interactions is not constantâ€”it is an unsteady or variable form of friction. This means that even when the external conditions like temperature, pressure, or load remain the same, the frictional behavior at the interface can still change over time. These variations may be due to factors such as micro-scale deformations, surface wear, or changes in the interfacial bonding. As a result, the frictional response becomes more complex and less predictable, making it essential to consider dynamic effects in modeling and analyzing such systems. Understanding these behaviors is crucial for applications ranging from micro-mechanical systems to biomedical devices where polymer-surface interactions are common.
