Adhesive wear is a type of wear that occurs when two surfaces come into contact and stick together, leading to material loss. This process often happens in mechanical systems where moving parts rub against each other, causing tiny pieces of material to transfer from one surface to another. The main factors influencing adhesive wear include the materials involved, surface roughness, and the presence of lubrication. Proper lubrication can help reduce adhesive wear by creating a barrier between surfaces, minimizing direct contact and friction. Understanding adhesive wear is essential for improving the longevity and performance of machinery.
