Kontaktipakastus
Kontaktipakastus is a Finnish term that translates to "contact freezing" or "contact tempering" in English. It refers to a heat treatment process used primarily in the metalworking industry to improve the hardness and wear resistance of specific areas of a metal component. Unlike through-hardening where the entire object is heated and quenched, kontaktipakastus involves selectively heating only the surface layer that requires enhanced properties.
The process typically involves rapidly heating the desired surface area using methods like induction heating or
Kontaktipakastus is advantageous when only specific wear surfaces or functional areas of a part need to be
