  "term": "Case-hardened",
  "field": "Industrial and trades",
  "definition": "Describing a metal component that has undergone a thermochemical treatment to create a hard, wear-resistant surface layer while retaining a softer, tougher core. This surface modification is achieved by diffusing elements like carbon or nitrogen into the outer material. Case-hardened parts exhibit improved resistance to abrasion and fatigue, commonly found in gears and shafts.",
