Challenges of aluminium and steel: sticking abrasive wear

摘要

Sticking. There are two primary challenges with forming aluminium alloys. The first is sticking of the aluminium to the surface of the tool. Sticking of ' aluminium looks similar to galling of steel, but the mechanism that creates the sticking is different. When steel material picks up on or galls the surface of a tool, it is the result of dynamic friction between the two surfaces. The level of galling can be managed by minimizing the amount of dynamic friction present.
