Case 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 … Wikipedia
Induction hardening — is a form of heat treatment in which a metal part is heated by induction heating and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to… … Wikipedia
surface 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… … Universalium
induction hardening — Method of heating cast iron (e.g., valve seats) to approx 1700° F which hardens it to a depth of 0.05 to 0.08 inches … Dictionary of automotive terms
глубина прокаливаемости — [depth of hardening (baking) zone] толщина поверхностного слоя стального изделия, в котором при закалке формируется структура мартенсита (или 50 % мартенсита + 50 % троостита).

steel — steellike, adj. /steel/, n. 1. any of various modified forms of iron, artificially produced, having a carbon content less than that of pig iron and more than that of wrought iron, and having qualities of hardness, elasticity, and strength varying … Universalium
Iron ore — Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the … Wikipedia
