This has been made feasible because steel is strong, flexible, and durable, thus, making it a suitable material for construction. However, there are instances where some modifications have to be made to the metal to make it suitable for some types of construction. The resolve to have steel that is strong, tough, wear, and shock resistant leads engineers to manipulate the surface of the metal, leaving its inner core intact (Davis, 2003). This process is called surface hardening of steel, and it can be done in many ways. Surface hardening techniques can be grouped into two main categories; local thermal treatment and thermochemical processes. ...
