 Wear  is a complex field and there are numerous types of wear. Different types (and combinations) of wear mechanisms requires different approaches to the material selection and design.

     Abrasive Wear – occurs when a hard-rough surface slides across a softer surface. Generally, to reduce abrasive wear you need a harder material. 

     Erosive Wear – occurs when particles impact the wear surface. As well the gradual removal of material from cutting and gouging actions, the kinetic energy of the impacting particles can cause surface work hardening and micro cracking which can result in delamination and spalling. 

     Corrosive Wear -This kind of wear is a mixture of corrosion & wear. The mechanical wear can be significantly increased by chemical reaction between the worn material and the corroding medium in the application environment. Material selection is very important to optimise the corrosion-wear properties of the component.

      Shenyang Gongda  can offer numerous types of wear resistant castings, including Ni-Hard, Hi-Chrome Iron, White Irons, High Manganese Steels, High Chrome Steels, Martensitic Steels, Copper alloys, etc. to meet the arduous conditions in quarrying,  coal, cement and mining and other manufacturing industries.
