Different types of wear mechanisms require different materials and designs.

Wear is a complex field with many types of wear. Different mechanisms of wear—and their combinations—require tailored material selections and design approaches. So, which type of wear do wear-resistant castings belong to?

Abrasive wear occurs when a hard, rough surface slides over a softer one. Generally speaking, to minimize abrasive wear, you’ll need a harder material. Applications include chutes and hoppers, which are prone to sliding wear.

Erosive wear occurs when particles collide with a worn surface. As material is gradually removed during cutting and air-arc gouging processes, the kinetic energy of impacting particles also leads to work-hardening and microcracking on the surface, ultimately resulting in delamination and spalling. Considering factors such as material toughness, material hardness, and equipment design—like particle impact angle and velocity—is crucial for effectively controlling erosive wear. Applications include pneumatic and hydraulic conveying systems, grates, screens, and cyclone separators.

Corrosive wear—this type of wear is a combination of corrosion and mechanical abrasion. Chemical reactions between the abrasive material and corrosive media present in the application environment can significantly accelerate mechanical wear, such as in paddle mixers used in superphosphate production. Material selection is crucial for optimizing the corrosion-wear performance of components.
