Quenching thiab tempering yogkev kho cua sov rau cov phaj siab zoo. quenching thiab tempering muaj ob theem kev kho cua sov. Theem 1 muaj xws li hardening, uas lub phaj yog austenitized rau kwv yees li 900 ° C thiab ces txias sai.

quenching thiab tempering txhais li cas?

Quenching thiab tempering yog txheej txheem uas ntxiv dag zog cov ntaub ntawv xws li hlau thiab lwm yam hlau-raws li alloys. Cov txheej txheem no ntxiv dag zog rau cov alloys los ntawm cua sov cov khoom thaum ib txhij txias hauv dej, roj, yuam cua, los yog gases xws li nitrogen.

Koj puas npau taws ua ntej lossis tom qab quenching?

Nyob hauv nws lub xeev nyuaj thiab nkig, cov hniav quenched yuav tawg zoo li iav yog tias poob, nws yuav tsum tau tempered ua ntej nws yuav muab siv. Tempering muaj cua sov cov hniav mus rau qhov kub tsis tseem ceeb (350 - 450 F) kom soften cov hlau me ntsis (Kuv siv lub qhov cub hauv chav ua noj).

Qhov txawv ntawm quenching thiab tempering yog dab tsi?

Quenching yog txheej txheem ntawm kev ua kom txias sai sai tom qab kev kho cua sov ntawm lub workpiece, thaum tempering yog txheej txheem uas muaj kev kho cua sov kom nce qhov toughness ntawm hlau-raws li alloys.

quenching thiab tempering ua rau lub microstructure yog dab tsi?

Cua sov cov khoom saum toj no qhov ntsuas kub tseem ceeb ua rau cov pa roj carbon thiab lwm yam khoom nkag mus rau hauv cov tshuaj. Quenching "freezes" lub microstructure , ua rau muaj kev ntxhov siab. Cov khoom yog tom qab tempered hloov pauv microstructure, ua tiav qhov tsim nyog hardness thiab tshem tawm cov kev ntxhov siab.
