ASM Case Hardening of Steel - Digital Course

摘要

This digital course examines case hardening as an important part of heat treating. It is particularly useful for the manufacture of machine parts, carbon steel forgings and carbon steel pinions. In many metallurgical applications, strength is of minor importance and wear resistance is the major consideration. In other applications where wear resistance is still the prime consideration, a high level of strength and considerable toughness are also required. To produce these conditions, it is necessary to employ specialized techniques that result in a relatively thin surface layer of the steel being space hardened. This thin layer is termed the case and the technique to produce the layer is termed case hardening. In this self-guided digital course, students will learn - with the help of rich visuals, narrated animations, and interactive quizzes - the different case hardening processes including carburizing, carbonitriding, and nitriding; quenching of case hardened parts; induction hardening; and the varibus types of furnaces used in commercial heat treating processes.
