  "term": "Case hardening",
  "field": "Industrial and trades",
  "definition": "A heat treatment process that creates a hard, wear-resistant surface layer, or case, on a metal component while maintaining a tough, ductile core. This is achieved by diffusing carbon or nitrogen into the surface of low-carbon steel. Common methods include carburizing, nitriding, and carbonitriding, with case depths ranging from 0.1 to 2.0 millimeters.",
