What is abrasion resistant cast iron ?
Abrasion resistant cast iron, we can also call it wear resisting cast iron. A certain amount of hardening phase distribute in the cast iron matrix which makes it not easy to wear. 1. Types of Abrasion resistant cast iron Abrasion resistant cast iron can be divided into antifriction cast iron and anti-wear categories. The former is working with lubricant, and adhesive wearing. Such as machine tool guide and carriage, large gearbox of tractors and so on. The latter is working in the absence of lubricant, and abrasive wearing, such as nut, sleeve and so on. Nut Sleeve 2. Antifriction cast iron There should be hard phase distributing in the soft tissue matrix, so after wearing ,soft substrate can form trench to make the film conducive to lubricate, withstand hard phase. Thin sheet of gray paralytic cast iron can basically meet this requirement. Ferrite matrix is the soft matrix, cementite is the hard phase, and graphite can be as the role of storing oil and lubricating. In order to further
