Module Type

E-learning

Description

Short description:
Learn how carburising enhances steel surface properties, including process steps, parameters, and microstructures.

Long description:
This module introduces the principles and industrial application of surface hardening through carburising. It explains the purpose of carburising in increasing surface carbon content to enhance hardness, wear resistance, and fatigue performance. The module explores the full carburising process, including preheating, controlled atmosphere treatment, quenching, and tempering, as well as the influence of key parameters such as time, temperature, and environment composition. It also examines alternative carburising methods, including cyanide-based processes, and their chemical reactions, advantages, and limitations. Finally, the module analyses the resulting microstructure of case-hardened steels, distinguishing between core and surface properties, and explains how these affect performance and distortion.

What you will learn

- Explain the purpose and mechanisms of carburising in surface hardening processes
