Kalení

Kalení je proces tepelného zpracování používaný především u ocelí ke zvýšení tvrdosti, pevnosti a odolnosti proti opotřebení. Kov se zahřeje nad kritickou teplotu (obvykle 750–900 °C v závislosti na obsahu uhlíku), až se jeho struktura změní na austenit. Následně je rychle ochlazen (kalen) ve vodě, oleji, polymerním roztoku nebo na vzduchu.
Rychlé ochlazení přemění austenit na martenzit, který je velmi tvrdý, ale křehký. Po kalení obvykle následuje popouštění.

Používané typy pecí:
• Elektrická muflová pec
• Komorová pec
• Indukční pec
• Solná lázeň

Použití:
Řezné nástroje, lisovací formy, ozubená kola, hřídele, ložiska
