How does the cost of surface hardening compare to the cost of using more expensive through-hardened materials?

Apr 12, 2010 ... So my concern is how to harden the surface to make it less absorbing for the sound wave. Any of you considered that? For a start I thought about ... May 22, 2024 ... Some of the most common types of hardening processes are carburizing, nitriding, induction hardening and flame/laser surface hardening. Case-hardening by carburising in solid, liquid and gaseous medias is discussed, together with heat treatment after carburising. Nitriding and ion-nitriding ... $559.99 Original price was: $559.99. $349.99 Current price is: $349.99. COLOR GRADIENT PATINA FOR STEEL ART BLUE HALO™. Rated 5.00 out ... While through-hardened steel offers an incredible degree of toughness and increased resistance to corrosive agents, the process makes the steel more brittle. Sep 13, 2009 ... This month we shall look at the final and probably most important stage of heat-treatment, namely that of surface treatments, especially nitride hardening. This paper presents numerical and experimental investigations of laser surface hardening of AISI 4340 using four different laser scanning patterns. A practical selection guide to help engineers and technicians choose the most efficient surface hardening techniques that offer consistent and repeatable ... Thermal Processing magazine focuses on the industrial heat-treating industry. Produced by Media Solutions Inc — publishers of Gear Solutions and Wind Systems ... The brief but intense heat of an electric spark, struck between an electrode and the steel surface, can harden a small volume of material.
