ruiskutemia
Ruiskutemia is a Finnish term that translates to "spray-tempering" in English. It refers to a process of heat treatment applied to certain metals, particularly steel, to improve their hardness and wear resistance. This method involves heating the metal to a specific temperature and then rapidly cooling it, typically by immersing it in a quenching medium like water or oil. The rapid cooling causes the formation of martensite, a very hard microstructure.
Following the quenching process, a tempering step is applied. Tempering involves reheating the hardened metal to
Ruiskutemia is commonly employed in the manufacturing of tools, springs, and other components that require high
