Kodi kutentha ndi chiyani?

Kutentha ndi njira yochizira kutentha yomwe imatenthedwaaloyimankhwala zitsulo kapena zigawo zina kutentha, akugwira kwa nthawi inayake, ndiyeno kuziziritsa mwa njira inayake.Tempering ndi opareshoni yomwe imachitika pambuyo pozimitsa, ndipo nthawi zambiri ndi workpiece yomwe imachitidwa kutentha.The ndondomeko otsiriza, kotero ophatikizana ndondomeko quenching ndi tempering amatchedwa chomaliza mankhwala.

2. Cholinga chachikulu cha kuzimitsa ndi kutentha ndi:
1) Chepetsani kupsinjika kwamkati ndi brittleness.Ziwalo zozimitsidwa zimakhala ndi kupsinjika kwakukulu komanso kupunduka.Ngati sakwiya msanga, nthawi zambiri amatha kupunduka kapena kusweka.
2) Sinthani zida zamakina a workpiece.Pambuyo kuzimitsa, workpiece ndi mkulu kuuma ndi brittleness.Pofuna kukwaniritsa zofunikira zosiyanasiyana zamagulu osiyanasiyana, kuuma, mphamvu, pulasitiki ndi kulimba kungasinthidwe kupyolera mu kutentha.

3) Khola workpiece kukula.Kutentha kumatha kukhazikika kapangidwe ka metallographic kuwonetsetsa kuti sipadzakhalanso kupunduka pakagwiritsidwa ntchito motsatira.
4) Sinthani magwiridwe antchito azitsulo zina za alloy.
Njira yozimitsira ndi kutenthetsa imathandizira kwambiri kukonza bwino kwasimenti carbide.Zonse zamakonotungsten carbide ozizira mutu nkhunguadzazimitsidwa ndi kupsya mtima pambuyo pa sintering.
