Edzés (Hardening)

Az edzés egy hőkezelési folyamat, amelyet elsősorban acéloknál alkalmaznak a keménység, szilárdság és kopásállóság növelésére. A munkadarabot a kritikus hőmérséklet fölé hevítik (általában 750–900 °C, a széntartalom függvényében), amíg az ausztenites szerkezet kialakul. Ezután gyorsan hűtik (tremp), vízben, olajban, polimeroldatban vagy levegőn.

A gyors hűtés átalakítja az ausztenitet martenzitté, amely nagyon kemény, de törékeny. Az edzést rendszerint utólagos lágyítás (popouštás, temperálás) követi.

Használt ipari kemencetípusok:

  • Elektromos muffelkemence
  • Kamrakemence (Box Furnace)
  • Indukciós kemence
  • Sófürdős kemence

Alkalmazások:

Vágószerszámok, sajtolóformák, fogaskerekek, tengelyek, csapágyak
