hardening treatment
11Case hardening — or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material s surface, forming a thin layer of a harder alloy. Case hardening is usually done after the part in question …
12Work hardening — Work hardening, also known as strain hardening or cold working, is the strengthening of a metal by plastic deformation. This strengthening occurs because of dislocation movements within the crystal structure of the material.[1] Any material with… …
13Diffusion hardening — Schematic cutaway view of a diffusion hardened metal gear Diffusion hardening is a process used in manufacturing that increases the hardness of steels. In diffusion hardening, diffusion occurs between a steel with a low carbon content and a… …
14Shock hardening — is a process used to strengthen metals and alloys, wherein a shock wave produces atomic scale defects in the material s crystalline structure. As in cold work, these defects interfere with the normal processes by which metallic materials yield… …
15surface hardening — ▪ metallurgy treatment of steel by heat or mechanical means to increase the hardness of the outer surface while the core remains relatively soft. The combination of a hard surface and a soft interior is greatly valued in modern engineering… …
