Călire

Călirea este un proces de tratament termic utilizat în principal pentru oțeluri, pentru a crește duritatea, rezistența și rezistența la uzură. Metalul este încălzit peste temperatura critică (în general 750–900°C, în funcție de conținutul de carbon) până când structura devine austenitică. Apoi este răcit rapid (călit) în apă, ulei, soluție polimerică sau aer.

Răcirea rapidă transformă austenita în martensită, care este foarte dură, dar fragilă. Călirea este de obicei urmată de revenire.

Tipuri de cuptoare utilizate:

  • Cuptor electric cu muflă
  • Cuptor tip cameră (box)
  • Cuptor cu inducție
  • Cuptor cu baie de săruri

Aplicații:

Scule așchietoare, matrițe, roți dințate, arbori, rulmenți
